Question

What happens to particles at a higher temperature?

A)speed up
B)slow down
C)remain constant
D)they double in size

Answer 1

A

Step-by-step explanation:

With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. ... With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly.

Answer 2

A.) Speed up

Step-by-step explanation:

Heat is directly proportional to kinetic energy which happens when the particles are moving very quickly. This means that more speed = more heat.
