Question

if energy is transferred to a substance as heat,will the temperature of the substance always the increase? explain why or why not

Answer 1

not always will added heat raise the temperature

a material @ its melting point, like water @ 0 Celsius,  will use the heat to melt the ice , before the temp would ever go up... the heat of fusion

a material @ its boiling point, like water @ 100Celsius, will use the heat to vaporize the liquid into gas without raising the temp... the heat of vaoprization

then there is the heat of sumlimation , & of solution .....
