Heat Transfer II

Conduction is different than convection because

• it involves direct contact between objects

• it doesn't require matter/medium to travel

• it involves fluids heating up and moving

• it is from the Sun

Convection is different than conduction because it

• involves fluids transferring heat from one place to another

• travels by electromagnetic waves

• involves objects directly touching

• gets things heated up faster

Radiation doesn't require a medium/matter to transfer heat.

• True

• False

The higher the temperature of an object, the _______ the particles are moving

• faster

• colder

• slower

• hotter

When something heats up, its particles begin to move faster. Therefore thermal energy is really a form of

• chemical energy

• gravitational energy

• kinetic energy

• electrical energy

Temperature is a measure of the average ________ energy of particles in an object.

• potential

• mechanical

• kinetic

• chemical

Conduction, radiation and convection are all

• methods of warming up

• types of heat transfer

• types of heating

• ways in which the sun heats us up

Safety blankets are worn to keep you

• warm as they reflect radiation back in

• warm as the reflect radiation away

• cool because they reflect radiation in

• cool because they are thin

A silver metal block and a black metal block are heated with a lamp. This type of heating is:

• convection

• radiation

• conduction

• insulation

A silver metal block and a black metal block are heated with a lamp. After 10 minutes, what block would be the hottest?

• silver block

• black block

• both blocks would be the same

• both would be different
