What happens when you apply thermal energy (heat up something)?
The molecules move faster
The molecules slow down
The molecules stop moving
When you mix two substances together, and one is warmer than the other, what will be the outcome (result)?
The faster molecules of the hotter substance will collide with the slower molecules from the colder substance, And eventually, they will reach the same temperature (speed)
They will not mix, since a hot substance and a cold substance will not interact, due to the fact that the colder molecules are not moving
Hot things have ____________ thermal energy than cold things
more
less
same
potato

True
False
You have dropped your popsicle and are watching it become a LIQUID. Which answer BEST explains what PHASE CHANGE has occurred AND how the molecule MOVEMENT has changed?
The PHASE CHANGE that has occurred is CONDENSATION and the molecule MOVEMENT has become FASTER.
The PHASE CHANGE that has occurred is EVAPORATION and the molecule MOVEMENT has become SLOWER.
The PHASE CHANGE that has occurred is MELTNG and the molecule MOVEMENT has become FASTER.
