Thermal Energy

Conduction is heat transfer by -

• Touch
• Circles
• Waves

Convection is heat transfer by-

• Touch an object
• The heating and cooling of a fluid
• Electromagnetic Waves

The sun warming your skin is an example of heat transfer through 

• conduction
• convection
• radiation
• thermal electricity

Heat transfer always goes from-

• Cold to Hot
• Hot to Cold
• Heat doesn't transfer
• Freezing to Cold

What happens to particles as they heat up?

• They slow down
• Nothing
• They don't move
• They speed up

What happens to particles as they cool down?

• They slow down
• Nothing
• They don't move
• They speed up

Conduction, Convection and Radiation are three types of...

• Electrical energy
• Thermal Energy
• Chemical Energy
• Sound Energy

In the formula, which quantity represents the specific heat?

• c

• m

• Q

• deltaT

The specific heat of copper is 0.385 J/g·°C. Which equation would you use to calculate the amount of heat needed to raise the temperature of 0.75 g of copper from 7°C to 29°C?

• Q = 0.385 J/g·°C x (29°C – 7°C)

• Q = 0.75 g x 0.385 J/g·°C x 29°C

• Q = 0.75 g x 0.385 J/g·°C x 22°C

• Q = 0.75 g x 0.385 J/g·°C x 7°C

What property of an object is related to the average kinetic energy of the particles in that object?

• conductivity

• temperature

• specific heat

• mass
