A 750 g aluminum pan is removed from the stove and plunged into a sink filled with 10.0 liters of water at 20.0 ° C. The water temperature quickly rises to 24.0 ° C. What was the original temperature of the pan in degrees Celsius and degrees Fahrenheit?

Explanation / Answer

heat gain by water in reaching 24 degree celcius = m c delta T = 10000*4.2*4 = 168 KJ

heat gain by allumium body = 750*0.910 (J/g/K) * delta T

heat gain by water = -heat lost by alluminium pan

168000J = -675 *deltaT => deltaT = -248.88

297 -T0 = -248.88

T0 = 272.88 degree celcius .
