ENERGY TRANSFER AND CONDUCTIVITY

__________ is a type of system that does not exchange matter or energy from its environment.

• open system

• all systems

• no system

• closed system

There are three ways energy could be transferred. Which one is not included.

• conduction

• radiation

• convection

• temperature

What does this diagram show?

• specific heat of substances

• how thickness affect transfer of energy

• thermal equilibrium is reached

• thermal absorption

Thermal energy transfers _______________________.

• when temperatures are equal.

• from higher temperature to lower temperature.

• from lower temperature to higher temperature.

• because both objects have high temperatures.

(a)   is transfer of thermal energy through a space [vacuum] using electromagnetic waves.

(a)   is thermal energy transfer that occurs in liquids and gases. It involves rising of warmer particles and sinking of cooler particles.

(a)   is thermal energy transfer that occurs in objects that are in contact with each other.

It measures the radiation given off by objects. What is it?

(a)  

___________ is the ability of a material to conduct heat.

• specific heat

• thickness

• surface area

• conductivity

The substance with more mass takes more energy from the surroundings to increase the kinetic energy of the particles. This relationship is called _______________.

• directly proportional

• inversely proportional

• not proportional

• high proportion
