2.Only heavy matter has density.
3.All solids, liquids, and gases have density.
4.Only solid matter has density.
Answer:
all solids, liquids and gases have density
The types of matter which property of density can be attributed with are;
.All solids, liquids, and gases have density.
Density can be regarded to as one of the characteristic property of a substance. The density of a substance expressed the relationship that the particular substance has with the mass of the substance as well as its volume which is how much space it takes up.The mass of a particular atoms, as well as how they are been arranged and their size, determine the density of a substance.Both solid , liquid as well as gas has density.For instance, density of water is 1000kg/cm^3Therefore, option C is correct.

How many atoms of H are there?
Answer:Explanation:
ther are 4
Answer:
First off, 3.4 / 342 = 0.01, not 0.001, so moles H = 0.22, not 0.022.
Then you multiplied the erroneous 0.022 x 6.022 x 10^22. Avogadro's number = 6.022 x 10^23, not 10^22! So your final answer should be 1.3 x 10^23 H atoms (choice B).
Your reasoning was right on, just a few math errors.

If you could repeat the lab and make it better, what would you do differently and why?
There are always ways that labs can be improved. Now that you are a veteran of this lab and have experience with the procedure, offer some advice to the next scientist about what you suggest and why. Your answer should be at least two to three sentences in length.
Writing the Lab Report
Now you will use your answers from the four questions above to write your lab report. Follow the directions below.
Section I: Overview of Lab
Use your answers from questions 1 and 2 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this lab and how it was completed. It should be one to two paragraphs in length.
Section II: Observations and Conclusions
Use your answers from questions 3 and 4 as the basis for the second section of your lab report. This section provides your reader with charts, tables, or drawings from the lab. You also need to include answers to the follow-up questions and ways in which you would improve the lab.
Overall
When complete, the lab report should be read as a coherent whole. Make sure you connect different pieces with relevant transitions. Review for proper grammar, spelling, punctuation, formatting, and other conventions of organization and good writing.

Water waves are surface waves. The energy of the waves moves
Question 2 options:
only perpendicular to the motion of the wave.
both parallel and perpendicular to the wave.
only parallel to the motion of the wave.
Answer:
Explanation:
Waves are actually energy passing through the water, causing it to move in a circular motion. ... This phenomenon is a result of the wave's orbital motion being disturbed by the seafloor.
The direction a wave propagates is perpendicular to the direction it oscillates for transverse waves. A wave does not move mass in the direction of propagation; it transfers energy.

How are mixtures and solutions different?
1.Unlike a solution, a mixture has density and will always sink in a liquid because mixtures lack buoyancy.
2.Unlike a solution, a mixture can dissolve completely in a liquid because the properties of the ingredients change.
3.Unlike a solution, a mixture is unable to change states of matter from a solid to a liquid or gas.
4.Unlike a solution, a mixture can easily be separated and each ingredient keeps its physical properties.
Answer:
The answer is 4.

How could you use a model to show the cause-and-effect relationship between Earth's rotation and the apparent motion of the stars across the night sky?
Question:
How could you use a model to show the cause-and-effect relationship between Earth's rotation and the apparent motion of the stars across the night sky?
Answer:
Gravity? or density because of the pull from the sun.
We can describe the cause-and-effect by showing the rotation of earth and its effect on the apparent motion of the stars across the night sky.
What is rotation of Earth?Rotation of earth means, spinning motion of earth at its own position as a result of which day and night will occur.
Because of the motion of earth will night occur and at the night time stars will travel from east to west direction. And polar starts will rotate with the pole star at center making a circular trial.
Hence, the above model is used.

A student makes a sandwich with several layers of bread and cheese. Then the student cuts the sandwich and says it models how a fault cuts through rock layers after the rock layers formed. Explain how the example of the sandwich relates to relative dating.
Answer:
Rock layer and sandwich layer is almost the same.
Why are rock layers are like sandwiches?
This geologic structure is called an anticline. Now gently bend your sandwich so that the layers are bowed downwards, thus creating a syncline. The presence of anticlines and synclines indicate strong forces that often form mountain ranges.
A student makes a sandwich with several layers of bread and cheese. Then the student cuts the sandwich and says it models how a fault cuts through rock layers after the rock layers formed. This example of the sandwich relates to relative dating where a geologist interprets how the earth was made by interpreting which rock layer and geological processes came first, second & third.
What is Relative Dating?Relative dating in geology is the method for determining the approximate age of a structure based on its physical relationship to surrounding geologic structures.
This is a qualitative process of determining the sequence of events. With an understanding of rock formation, geologists can sequence structures to determine the order of events and relative age.
Rock layers are formed first in flat layers. Therefore, if they're are tilted because it got squished, then the tilting came after it was laid down.The oldest layer is on the bottom and the youngest layer is on top.If the layers are cut by a fault, the cut is the youngest process.If the layers are cut or filled, from an igneous intrusion, the igneous intrusion is the youngest process.Therefore, A student makes a sandwich with several layers of bread and cheese.

Tsunamis are huge waves that carry large amounts of energy across the ocean. They are often caused by underwater earthquakes. One a tsunami forms, the wave can travel hundreds of kilometers before reaching land. Are the water molecules that touch land the same ones that the earthquake initially moved? Why or why not?
Answer:
Some of them yes but some of them no.
Explanation:
When the tsunami moves across other bodies of water it initially gets bigger. When it is moving across the water it is picking up molecules as well as dropping them off. But the farther away the tsunami gets from the water the smaller it gets.
Some of the water on land may be initaited by earthquake or may be not.
What is tsunami?Tsunami is a natural disaster, which causes the large destroy of natural lands, forests, habitats of many living beings, etc.
As it is mention that tsunami is caused by the earthquake which is occured underwater and as a effect of this, waves of ocean can travel hundreds of miles before touching the land. So, it is not necessary the water molecules which touches the land after this disaster is always that ones which are initiated by the earthquake.
Because during the travelling process may be some water will again drop off in the ocean or some may get evaporate.
Hence, it may be the water initiated by the earthquake or may be not.

what happens when a low air pressure seytem meets a high air pressure
Answer:
The temperature of the air drops to below freezing. 2. The air moves to the low pressure system, creating wind. 3.The precipitation is removed from the air. 4. The air starts blowing in an easterly direction.
Explanation:
Answer:
The slightly inward moving air in low pressure causes air to converge and since it can't move downward due to the surface, the air is forced upward, leading to condensation and precipitation as discussed earlier. The opposite occurs with high pressure.
