The amount of energy which is required to raise the temperature of 0.2 kg of aluminum from 15°C to 18°C is 49,545 J.
How do we calculate absorbed energy?
Amount of energy absorbed by any material will be calculated by using the below equation:
Q = mcΔT, where
m = mass of aluminum = 0.2 kg
c = specific heat of aluminum = 897 J/kg.K
ΔT = change in temperature = 18 - 15 = 3°C = 276.15 K
On putting these value on the above equation, we get
Q = (0.2)(897)(276.17) = 49,544.89 = 49,545 J
Hence required amount of energy is 49,545 J.
