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☺️​

Respuesta :

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 ;)

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
