Question:

Answer 1

How does the kinetic energy of a substance's particles in the gas phase compare to their kinetic energy in the solid phase? (1 point)

The kinetic energy of the solid and liquid phases is the same.
The particles have less kinetic energy in the gas phase than in the solid phase.
The particles have more kinetic energy in the gas phase than in the solid phase.
The kinetic energy of the substance's particles will depend on the volume of the substance.


Which of the following best explains what happens when the kinetic energy of particles in a solid state increases? (1 point)

They vibrate so quickly that the particles ionize and become plasma.
They vibrate so slowly that the particles are no longer held together, resulting in a gas.
They vibrate fast enough to overcome the forces of attraction holding them together and become a liquid.
They vibrate more slowly, causing the forces of attraction holding them together to increase, resulting in a liquid.

Answer 2

@Abhisar I am going with the third option on both of these

Answer 3

Is this a test question?

Answer 4

yes, these are questions that are from a study guide

Answer 5

I hope it's not from an on going test.

Answer 6

no it's not, its for my own practice :)

Answer 7

ok, try not to include that (1 point) thin in ur question.

Answer 8

oh I'm sorry

Answer 9

Particles of solid has the least amount of energy and they are almost fixed to their place. As we provide energy the phase starts to change and thus particles of liquids have much more kinetic energy than solids. this is the reason their particles vibrate much more vigorously. Particles of gases have the maximum amount of K.E.

Answer 10

i see

Answer 11

when the solid state increases, do the particles move fast or slow
