Chelsea went ice skating. The ice, her skates, the Zamboni, and the rink building were all examples of solids she encountered. She developed a model of the particles in the ice. Which of statements about the particles present in her model of solid are true?????? Choose the statements that apply.

A. they vibrate in place
B. they slide past each other
C. they are packed very closely together
D.they cause the solid to have a definite volume and definite shape



I think it is d c and a I may be wrong☺️​

Answers

Answer 1

Answer:

Answers are C, D

Explanation:

Solid particles always stick together no matter what happens unless it is changing into a liquid. If you are talking about vibration for solid particles that only applies to thermal vibratio so not A. They do not slide past each other because they are packed very tightly together. They have a definite shape and volume because they stay together unless facing heat. Hopefully this helps you :)

pls mark brainlest ;)

Answer 2

The statements about the particles present in her model that are true;

C and D

They are packed very closely together ( C ) They cause the solid to have a definite volume and definite shape ( D )

Particles of solids are closely packed and this feature distinguishes a solid from other forms of matter ( liquid and gas ). Solids have a definite volume and shape due to their closely packed particles.

Vibration in solids occur when solids are under thermal pressure and from her skating activity, there was no form of thermal pressure therefore solids vibrating in place would not be included in her model.

Hence we can conclude that The statements about the particles present in her model that are true; they are packed very closely together and  They cause the solid to have a definite volume and definite shape

C. The molecules of a gas are much further

D. The molecules of a solid are much larger

Answers

C) The molecules of a gas are much further

apart than those of a solid.

A gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.

What are gases?

Gases is one of the four fundamental state of matter.

Gases can be defined as phase of matter that neither have fixed shape nor have fixed volume.

The molecules of gases are far apart from each other as compare to other phases of matter.

The change in properties of volume is known as compressibility and those fluid whose volume changes are known as compressible fluids or gases.

The fluids which does not compressed or expanded and its volume remain constant are known as incompressible fluids or gases.

Thus, gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.

Describe how you would measure the density of a boat (how would you predict if it would float )

Answers

Answer:

Please find the description below

Explanation:

The density of a substance refers to its mass per unit of its volume i.e the amount of a substance contained in a given volume. The density is calculated using the formula:

Density = mass/volume

Using this formula, with the known value for mass and volume of the boat, the density of the boat can be calculated.

An object will FLOAT on a liquid substance if its density is lower than that of the liquid while it will SINK if it has a higher density than that of the liquid.

In this case, with a known density of water, which is 1g/cm^3 or 1000kg/m^3,

a boat placed on water will FLOAT if its density is <1g/cm^3 (less than) while it will SINK if its density is >1g/cm^3 (greater than).

Answers

Answer:C.) It has one group in which the manipulated variable is tested, and another in which the responding variable is tested

Explanation: hope this helps

The statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested (option C).

What is a controlled experiment?

A controlled experiment is an experiment where one variable is tested at a time and all other variables are kept constant.

An experiment consists of a manipulated or independent variable, which is the variable changed, and a responding or dependent variable, which is the variable measured.

Therefore, statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested.
