Answer to Question #59827 in Physics for Joshua

Question

An electric heater raises the temperature of 120g of water in a thin light vessel through 10K IN 2min,when placed in 70g of water contained ina metal vessel of mass 0.55kg the temperature rises through 9K in the same time. Calculate from the above :
i. The heat supplied in 2min by the heater
ii. The power of the heater
iii. The heat supplied to the metal vessel
iv. The heat capacity of the vessel and the specific heat capacity of its materials.
[S.H.C of water =4.2Jg-1K-1]
