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 ?

A liquid at 30°C is poured verly slowly into a Calorimeter that is at temperature of 110°C. The boiling temperature of the liquid is 80°C. It is found that the first 5 gm of the liquid completely evaporates. After pouring another 80 gm of the liquid the equilibrium temperature is found to be 50°C. The ratio of the Latent heat of the liquid to its specific heat will be ____C°. [Neglect the heat exchange with surrounding.]
