Answer:

The answer is c

Explanation:

Answer:

All three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does.

When a solid is heated, its atoms vibrate faster about their fixed points. The relative increase in the size of solids when heated is therefore small. Metal railway tracks have small gaps so that when the sun heats them, the tracks expand into these gaps and don’t buckle.

Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids. This is the principle behind liquid-in-glass thermometers. An increase in temperature results in the expansion of the liquid which means it rises up the glass.

Molecules within gases are further apart and weakly attracted to each other. Heat causes the molecules to move faster, (heat energy is converted to kinetic energy) which means that the volume of a gas increases more than the volume of a solid or liquid.

However, gases that are contained in a fixed volume cannot expand - and so increases in temperature result in increases in pressure.:

Answer:

Bb rabbit

Explanation:

In an ecosystem , when a brown  "BB" rabbit  is crossed to a white "bb" rabbit offsprings with genotype Bb are produced.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

B - ide

Explanation:

Answer:

Find the list below.

Explanation:

Good Use

1. Manufacture of substances: Virtually all manufactured substances incorporate water during their production.

2. Provision of electricity: Water in dams have been channeled to provide thermal energy.

3. Provision of transportation: Ships, boats, and canoes provide a means of transporting humans and goods to other places using water as a medium.

4. Provision of recreation: Swimming in pools are recreational activities.

5. Cleaning surfaces and the environment: Dust and other debris are removed from our homes and environments with the help of water.

6. Provision of food: The fishes obtained from water bodies serve as a food source.

Bad Use

1. Refuse dumping ground: Most industries and homes channel waste products into water bodies and this can be dangerous to aquatic lives.

2. Channels for oil spillage: Oil spillage is another environmental hazard caused by humans on water bodies.

Answer:

74.35 g

Explanation:

The equation  of the reaction is given as;

2Al2O3 --> 4Al + 3O2

From the reaction;

2 mol of Al2O3 reacts to produce 3 mol of O2

Converting 2 mol of Al2O3 to mass;

Number of moles = Mass / Molar mass

Mass = Number of moles * Molar mass

Mass = 2 * 101.96 = 203.92 g

Converting 3 mol of O2 to volume;

1 mol = 22.4 L

3 mol = x

x = 22.4 * 3 = 67.2 L

This means 203.92g of Al2O3 produces 67.2L of O2

xg would produce 24.5 L of O2

203.92 = 67.2

x = 24.5

x = (24.5 * 203.92) / 67.2

x = 74.35 g

Answer:

C. Moving Balloon 1 can make Balloon 2 move without the balloons touching.

Explanation:

When two balloons are rubbed with a wool cloth, they get electrostatic charge and both become negatively charged.

If both balloons will be place close together, balloon 1 will push the balloon 2 far from itself without touching it as they both are negatively charged and things with same charges repel each other.

Hence, the correct answer is "C. Moving Balloon 1 can make Balloon 2 move without the balloons touching."

Answer:

Using the coarse adjustment knob of the microscope in high power may lead to the breaking of the slide if adjusted and raised the slide too much which can damage the sample as well as the high power lens.

In this case, I would recommend using the fine adjustment knob and moving away from the end of the viewing area of the microscope so there would no collision take place. The fine adjustment will help to get a clear image.

Answer:

Gases

Explanation:

Gases have the highest kinetic energy of any state of matter and thus occur at the highest temperatures. Increasing the temperature of a gas in an open system will not further change the state of matter because the gas molecules will only become infinitely further apart.

Answer:

Gas

Explanation:

There are many forms in which temperature increases, for example sublimation, (solid to gas) which is essentially vaporization which happens during a sub-like gas phase concluding the answer to gas.

Answer:

The periodic table is a set of elements organized by their atomic number, from lowest (hydrogen 1) to highest (oganesson 118). That number is the amount of protons in the nucleus of an atom of the element. The table is split into three groups of elements (metals, nonmetals and metalloids). As you go down the table the elements are more reactive.

Answer:

[tex]\boxed {\boxed {\sf Hepta}}[/tex]

Explanation:

We are given the formula:

[tex]PCl_5[/tex]

This is a molecular formula, because it contains nonmetals.

1. Name the first element

The first element is phosphorous (P). Since this is the first element and there is only one, we don't need a prefix.

2. Second element

The second element is chlorine (Cl). It has a subscript of 5, so we must add the prefix of hepta-.

Add the ending of -ide.

The prefix used for the second element is hepta. The compound name is phosphorous heptachloride.

Answer:

C

Explanation:

n= 7.7mol

P= 9120pa

T = 329.15K

PV=nRT

V= nRT/P

V= (7.7×8.314×329.15)/9120

V= 2.308meter cubic

V= 2308L
