Question

When an object gains thermal energy, the molecules inside the object move faster.

True or False?

Answer 1

true

Step-by-step explanation:

when the heat rises the molecules inside vibrate much faster than when ever they cool down because they are slower, think of it as if you were frozen but could still move, you'd be slow but if you weren't and were warmer your system can work more and you can run faster than when you were frozen.
