H.P.3C Conceptual Understanding

H.P.3C Conceptual Understanding

by Mrs Plasquita

When there is a temperature difference between two objects, an interaction occurs in the form of a transfer of thermal energy (heat) from the hotter object to the cooler object.​

​H.P.3C

Multiple Choice

Heat transfer occurs when there is a temperature difference between two objects.

• TRUE

• FALSE

Thermal energy is the total internal kinetic energy of the molecules and/or atoms of a system and is related to temperature, which is the average kinetic energy of the particles of a system.

​H.P.3C

Multiple Choice

the total internal kinetic energy of the molecules and/or atoms of a system

• Mechanical Energy

• Thermal Energy

• Sound Energy

• Potential Energy

Energy always flows from hot to cold through the processes of conduction, convection, or radiation.
