Temperature, Thermal Energy & Heat

________________is a measure of the AVERAGE kinetic energy of the individual particles in an object. It tells us how hot or cold something is.

• Temperature

• Radiation

• Conduction

• Conjunction

Heat transfer by convection happens when:

• there is a circulation of a hot fluid rising and cold fluid sinking, creating a circulating current

• there is space that heat travels through in electromagnetic waves outwardly in all directions

• two objects are touching and heat moves from one object into the next object.

Kito puts his spoon into a helping of fresh, hot, mashed potatoes as shown in the picture. Which process takes place when the objects come together?

• The temperature of the spoon increases, but its thermal energy does not change.

• Energy in the form of heat is transferred by conduction from the warmer mashed potatoes to the cooler spoon.

• The thermal energy of both the mashed potates and the spoon increase as the energy in the form of heat is transferred between them.

• The average temperature of the spoon does not change.

How does the thermal energy of the liquid in the larger beaker compare to the thermal energy of the liquid in the smaller beaker?

• The liquid in the larger beaker has less thermal energy than the liquid in the smaller beaker.

• The liquid in the larger beaker has more thermal energy than the liquid in the smaller beaker.

• The liquid in the larger beaker has the same amount of thermal energy as the liquid in the smaller beaker.

• The exact volume of the liquid in each beaker must be known to compare the thermal energy of the liquids.

Temperature

• The total kinetic and potential energy of all the particles in an object.

• Energy that is transferred from a warmer object to a cooler object.

• A measure of the average kinetic energy of the particles in a substance.

• The heating of a substance that causes its particles to move more quickly.
