9.4.4 Heat vs Temperature + Evaporation (Mr. Chow)

The temperature of a substance increases as___.

• the substance expands
• the average kinetic energy of its particles increases
• the substance's volume increases
• the substance's mass increases

The transfer of thermal energy from a hotter region to a colder region is called _______ ___________

(a)  

If the particles of two substances have the same average kinetic energy, then___.

• the specific heats of the substances are identical 
• the particles will not react chemically
• the substances have equal thermal energies
• the substances have equal temperatures

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

A chair is several feet from a fireplace. The side of the chair facing the fireplace gets warm due to

• conduction
• convection
• radiation

If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL ____________

• one reaches a temperature of zero

• they both have an equal temperature

• one runs out of energy

Some cook pans have cooper on the bottom to heat evenly.
Copper transfers heat to the pan by

• conduction
• convection
• radiation

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

• conduction

• convection

• radiation

• insulation

Heat is transferred from one particle of matter to another via the vibration of particles it is a process called

• conduction

• convection

• radiation

• insulation

The transfer of heat energy by electromagnetic waves is called

• conduction

• convection

• radiation

• insulation
