2 kg water at `80^@C` is mixed with 3 kg water at `20^@C`. Assuming no heat losses, find the final temperature of the mixture

. 540 gram of ice at 0^@C is mixed with 540 gram of water at 80^@C . The final temperature' of the mixture is

When 0.15 kg of ice at 0^@C mixed with 0.30 kg of water at 50^@C in a container, the resutling temperature is 6.7^@C . Calculate the latent heat of fusion of ice. Given S_(water) = 4186J kg^-1 K^-1 .

When 0.2 kg of ice at 0°C is mixed with 0.40 kg water at 50°C,the resulting temperature is 7°C,Find latent heat of fusion of ice,(Give s-w=4186 Jkg^-1 K^-1)

One gram of ice at 0^@C is added to 5 gram of water at 10^@C . Final temperature of the mixture is

75 g of water at 100^@ C is added to 20 g of ice at -15^@C . Calculate the resulting temperature, give that latent heat of ice= 80 cal g^(-1)C^(-1) and specific heat of ice=0.5 cal g^(-1) C^(-1) .

A hot ball of iron weighing 200 g is dropped into 500 g water at 10°C .The resulting temperature is 22.8°C .Calculate the temperature of the ball

A pump lifts 20 kg of water in one minute to a vertical height of 30m.Find the power of the pump.

In an experiment on the specific heat of a metal, a 0.20 kg block of the metal at 150^@C is dropped in a copper calorimeter (of water equivalent 0.025 kg) containing 1-50 cm^3 of water at 27^@C . The final temperature is 40^@C . Compute the specific heat of the metal. If heat losses to the surroundings are not negligible, is your answer greater or smaller than the actual value for specific heat of the metal?

200 gram of a solid ball at 20^@C is dropped in an equal amount of water at 80^@C . The resulting temperature is 60^@C . This means that specific heat of solid is-

An electric heater takes 15 min to raise a certain quantity of water from 0°C to its boiling point.If it takes another 80 min to turn all water into steam ,find the latent heat of vaporsation of water.
