Answer: rate at which energy is being removed is 58.9J/s or 58.9W
Explanation:
Given;
Mass of water Mw =892g = 0.892kg
Mass of aluminium Ma = 214g = 0.214kg
Rate of change in temperature ∆T = 0.9°C per minute
Specific heat capacity of water Cw = 4186J/kgC
Specific heat capacity of aluminium Ca = 900J/kgC
Since both the water and aluminium are at thermal equilibrium and the decrease with the same rate, the energy removed per minute is given as;
Q = (MwCw + MaCa)∆T
Q = (0.892×4186 + 0.214×900)×0.9
Q = 3533.8608J per minute
To determine the energy being removed in watts
P = Q/t
P = 3533.8608J/60s
P = 58.89768W
P = 58.9W
