Thermal energy always flows from ​ (a)   ​ temperature objects to ​ (b)   temperature objects.

• higher
• lower

​ (a)   is the transfer of energy from one object to another.

• Heat
• thermal
• temperature

Why is there no such thing as "cold"

• nerves can't feel cold

• cold stops being cold after a while

• feeling the absence of heat

Transfer of thermal energy can happen in three ways, match the ways with their descriptions.

• through matter of direct contact

• radiation

• by the movement of heated particles

• convection

• through electromagnetic waves

• conduction

Match the following with the correct material for heat transfer.

Groups:

(a) Conductors

,

(b) Insulators

• styrofoam

• metal

• skin

• allow heat to flow easily

• do not allow easy heat flow

• plastic
