A body of mass 40g loses 80J of heat energy. If the specific heat capacity of the body is 400 Jkg^-1, calculate the change in temperature of the body.

Q=MCx, x= STAND FOR TEMPERATURE
Q=80J, M=40g to kg (because of the unit given by the specific heat capacity the mass there is in kg and not g)
40g to kg
1000g = 1kg
40g =
40/1000 = 0.04kg
Q=MC0
80 = 0.04 X400 X x
ans = 5.0k
