A vessel initially contains 200 kg of water at 60^(@)C . More water is supplied to the vessel from two taps. Temperature of water from the first tap is 80^(@)C and that from the second tap is 20^(@)C . Each tap supplies water at the rate of "5kg. min"^(-1) . After what time, will the temperature of water in the vessel be 55^(@)C ?

A solid of mass 70 g is heated and dropped in a calorimeter of water equivalent 10 g conaining 116 g of water. If the fall in temperature of the solid is 15 times the rise in temperature of water, find the specific heat capacity of the solid .

A 10 Watt electric heater is used to heat a container filled with 0.5 kg of water. It is found that the temperature of water and the container rises by 3, K in 15 minutes. The container is then emptied, dried and filled with 2 kg of oil. The same heater now raises the temperature of container-oil system by 2''K in 20 minutes. Assuming that there is no heat loss in the process and the specific heat of water as "4200 J . kg"^(-1).K^(-1) , the specific heat of oil in the same unit is equal to
