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.

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

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

____________ 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?

___________ 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
