Energy

Question 24

Answer 24

Sublimation

Question 25

You go into a coffee shop and thee whole place is filled with the pungent smell of freshly brewed coffee. Explain what is happening in terms of the Kinetic Theory of matter…

Answer 25

The atoms of the pungent smelling coffee bounces around the shop.

Question 26

Compare and contrast the phase changes of sublimation and deposition ( Tell how they are the same and different)

Answer 26

“Sublimation”– changing from a solid to a gas w/o passing through liquid. “Deposition” – changing from gas to a solid w/o passing through liquid. **They are opposites, but both do not pass through the liquid phase.

Question 27

What happens to the air pressure in tires on a hot day after a long road trip? Explain

Answer 27

The air pressure in the tire goes up because friction causes the temperature to increase. As temperature rises, pressure increases.
