Savvas Topic 4: Thermal Energy

This phase of matter has the most thermal energy

• gas

• liquid

• solid

The reason the temperature in the cups in the experiment above changes is because aluminum is

• thermally expanding

• a conductor

• an insulator

• a nonmetal

Water’s specific heat is 4,180 and iron’s is 450. Which will heat up faster?

• water

• iron

• oil

• air

Temperature scale starting with absolute zero at 0 is the

• coldness scale

• Farenheit scale

• Celcius scale

• Kelvin scale

Transfer of energy by electromagnetic waves is called

• conduction

• convection

• radiation

• infrared proton rays (sounds cool, but I made it up so don't pick this one)

The three scales used to measure temperature are

• metric, American and wrong

• Celsius, Fahrenheit, and Calvin

• Celsius, Fahrenheit, and Kelvin

A material that doesn’t allow heat to pass through it easily is a/an

• conductor

• insulator

• metal

• rock

The diagram above shows a Bunsen burner heating a beaker of water on a beaker stand. The arrows represent the transfer of heat energy in the water. Which process is primarily responsible for the transfer of heat in the beaker as indicated by the arrows in the diagram?

• conduction

• radiation

• convection

• condensation

The diagram above represents a thermometer. Which of the following best explains how the thermometer works?

• Liquid changes to a gas when heated.

• Gas changes to a liquid when heated.

• Liquids expand when heated and contract when cooled.

• Liquids contract when heated and expand when cooled.

Thermal energy is associated with

• kinetic and potential energy of particles

• position or shape

• chemical reactions

• chemical bonds
