Specific heat

Question 1

Specific heat

Answer 1

the amount of heat eenrgy(cal or J) needed to raise the temperature of 1 g of a substance by 1 C

Specific heat= heat/ mass x change in temperature

• the larger the specific heat, the less its temperature will change when its absorbs a particular amount of heat energy

Question 2

heating curve

Answer 2

shows how substances temperature changes as heat is added

Question 3

Phases

Answer 3

melting=endo
freezing=exo
vaporization=endp
condesnation=exo
sublimation=endo
depostion= exo
