A scientist proposes a new temperature scale in which the ice point is 25X (X is the new unit of temperature) and the steam point is 305X. The specific heat capacity of water in this new scale is (in J*kg^(-1)*X^(-1))

5 gm of ice at -10^@C are mixed with 20 gm of water at 39^@C . Will whole of the ice melt? If so, what is the final temperature of the mixture? Specific heat capacity of ice = 0.5 cal gm^-1 "^@C^-1 and latent heat of fusion of ice = 80 cal gm^-1 , specific heat capacity of water = 1cal gm^-1 "^@C^-1 .

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 Jkg^(-1) k^(-1) , the specific heat of oil in the same unit is equal to

The distance between the point on x axis and (3, 2, —4) is m unit.Find the co-ordinate of that point which lies on x axis

Water, flowing through a pipe at the rate of "0.15 kg.min"^(-1) , is heated by a 25.2 W heater. Temperature of the incoming and the outgoing water are 15.2^(@)C and 17.4^(@)C respectively. When the rate of flow of water is increased to "0.2318 kg.min"^(-1) and rate of heating to 37.8W, temperature of incoming and outgoing water remain the same. Find the specific heat capacity of water and the rate of loss of heat through the pipe.
