when its temperature is increased from 20.0°C to 50.0°C? The specific heat of water is 4.184 J/(g°C).,

Answered by maham237 @ 13/07/2021

Q = m . C . Δ T
q : Heat absorbed
m : mass of the sample
C : The specific heat of the substance.
Δ T : The change in temperature (Final T - initial T)
So:
q = 15.5 x 4.18 x (50 - 25) = 1619.75 J
