Changes in Temperature Module

Why the tracks are bent?

• the train was too heavy

• there was an accident

• the tracks heated and expanded

• the tracks cooled and contracted

What is this process?

• melting

• vaporization

• condensation

• evaporation

What is the image demonstrating?

• heating the system causes the particles to push further apart

• adding more particles to the system causes the balloon to expand

• volume increases as temperature decreases

• heat slows the particles allowing the balloon to get bigger

Why is the balloon deflated?

• the particles slowed down

• the particles got faster

• the particles became smaller

• the particles escaped the balloon

Thermal contraction is...

• a decrease in volume as temperature decreases

• an increase in volume as temperature decreases

• a decrease in volume as temperature increases

• an increase in volume as temperature increases

How does heat flow?

• from hotter objects to colder objects

• from colder objects to hotter objects

• in both directions (hot to cold AND cold to hot)

The amount of force per unit area applied to an object's surface...

• pressure

• temperature

• heat

• Star Wars

During the process of melting, the temperature does not change as energy is added. What is this energy doing?

• breaking the attractive forces between particles

• going into the atmosphere

• creating new particles

• increasing the temperature
