PHYSICS - Specific heat capacity

?
Give the definition of specific heat capacity
How much thermal energy it takes to increase the temperature of 1kg of a substance (e.g aluminium) by 1oC
1 of 5
what is the word equation that links energy transferred to specific heat capacity?
Change in thermal enegry (J)= Mass (kg) x specific heat capacity (J/kgoC) x Temperature change (oC)
2 of 5
what is the symbol equation for the change in thermal energy?

EXAMPLE QUESTION: An iron has an aluminium plate with a mass of 1.5kg. The temperature rises from 20oC to 200oC, the SHC of aluminium is 913J/kgoC. calculate the energy needed
1.5 (mass) x 913 (specific heat capacity) x 180 (temp change 200-20) = 246510J
4 of 5
Do metals usually have high or low specific heat capacities? Why?
Metals are good conductors of heat so typically have low specific heat capacities
