4. what happens when the temperature of an object increases? a. the object’s particles move close together b. the number of the object’s particles increases c. the object’s particles move faster d. the object’s particles stop moving

c.The object’s particles move faster

Explanation:

When the temperature of an object increases, the particles of that object gain kinetic energy and move faster.

Kinetic energy is related to motion. If an object has multiple particles, as faster they move, they will collision with each other.

So, the speed of the particles is related to the temperature. (And also the mass of the particle)

your answer is, orbit around the nucleus

a=d/t

a="triangle"v/t

explanation:

a = acceleration
