Specific heat is the heat absorbed or released by one gram of a substance during change of one degree centigrade or one Kelvin temperature .
Heat capacity is the heat absorbed or released by a substance during change of one degree centigrade or one Kelvin temperature.
Mass of water = 30.0 g.
Mass of aluminium cup = 60.0 g
Initial temperature of water = 20.0 0C.
Initial temperature of aluminium = 20.0 0C
Final temperature of both water and aluminium = 22.5 0C.
Q = ms ΔT
Q = heat absorbed / released.
m = mass of substance.
s = specific heat of substance.
ΔT = temperature change.
We know that:
Specific heat of aluminium = 0.900 J/gm 0C
Specific heat of water = 4.184 J/gm 0C
As given that both aluminium and water will absorb heat to raise the temperature.
Let us calculate the heat needed by each
Heat needed by water:
Q1 = mass ...
