A metal cylinder (mass = 0.80 kg, specific heat = 0.45 kJ kg⁻¹ K⁻¹) contains 2.00 kg of water at 20.0 °C. The cylinder‑water system is placed in a large water bath maintained initially at 80.0 °C. After 10.0 min the temperature of the cylinder‑water system rises uniformly to 45.0 °C. Assume that during this interval no heat is lost to the surrounding laboratory. Answer the following:

Question Parts

( a )
Calculate the total heat absorbed by the cylinder‑water system during the 10 min.
( b )
Determine the average rate of heat transfer (in watts) from the bath to the system over the 10 min period.
