Water is filled in a vessel which is kept in a room at a temperature of 20^(@)C . The temperature of the water is slowly increased. When the temperature of water is 40^(@)C , it loses heat at the rate of 10cal/s. What will be the rate of loss of heat when the temperature of water is 80^(@)C ?

What is the resulting temperature when 150 g of ice at 0^(@)C mixed with 300 g of water at 50^(@)C ?

The temperature of three liquids A, B and C are 14^(@)C, 24^(@)C and 34^(@)C respectively. When A and B are mixed in equal masses, the temperature of the mixture becomes 20^(@)C , when B and C are mixed in equal masses, the temperature of the mixture becomes 31^(@)C . If A and C are mixed in equal masses, then what will be the temperature of the mixture?

Two containers X and Y are filled with water at different temperature. When 10 g of water from container X is mixed with 20 g of water from container Y, the resultant temperature is found to be 20^(@)C . When 20 g of water from container X is mixed with 10 g of water from container Y, the resultant temperature is found to be 30^(@)C . Determine the inital temperature of water in container X and Y.
