An electrically heated coil is immersed in a calorimeter containing 360 g of water at `10^@C`. The coil consumes energy at the rate of 90 W. The water equivalent of calorimeter and coil is 40 g. The temperature of water after 10 min is

An electrically heating coil was placed in a calorimeter containing 360g of water at 10^(@)C . The coil consumes energy at the rate of 70W . The water equivalent of calorimeter and coil is 40g . Find temperature of the water after 10min . Given specific heat of water = 1 cal//g.^(@)C, 1 cal = 4.2J .

A thin metallic wire of resistance 100 Omega is immersed in a calorimeter containing 250 g of water at 10^@C and a current of 0.5 ampere is passed through it for half an hour. If the water equivalent of the calorimeter is 10 kg, find the final temperature of water.

A thin metallic wire of resistance 100Omega is immersed in a calorimeter containing 250g of water at 10^(@)C and a current of 0.5 ampere is passed through it for half an hour. If the water equivalent of the calorimeter is 10g, find the rise of temperature.

When 30 g water at 50^(@)C is poured into a calorimeter at a temperature 15^(@)C , the final temperature attained is 20^(@)C . What is the water equivalent of the calorimeter?

A calorimeter contains 70.2 g of water at 15.3^@C . IF 143.7 g of water at 36.5^@C is mixed with it, the common temperature becomes 28.7^@C . The water equivalent of a calorimeter is
