Heat transfer occurs

• In many directions.
• Both from warm objects to colder ones and from cold objects to warmer ones.
• Only from warm objects to colder ones.
• Only from cold objects to warmer ones.

As the thermal energy of matter increases, its particles usually spread out, causing

• Condensation
• Evaporation
• Vaporization
• Thermal expansion

Heated air moved from baseboard heaters to the rest of a room in a process called

• Conduction is how the air in the room is heated.
• Convection heats the room; radiation is what comes off of the baseboard heater.
• Radiation spreads due to the density differences in the room.
• Insulation traps the heat so the room does not get warm.

Which of these is a good conductor?

• Wood
• Paper
• Silver
• Air

A measure of the average kinetic energy of the individual particles in an object is called

• Thermal energy
• Conduction
• Convection
• Temperature

True or False: The more particles a substance has at a given temperature, the more thermal energy it has.

• True
• False

True or False: During conduction heat is transferred by the movement of currents within a fluid.

• True
• False

True or False: Trapped air is a good conductor because it reduces heat transfer.

• True
• False
