Find the amount of heat released if 1kg steam at 200^(@)C is convered into -20^(@)C ice.

If there is no heat loss, the heat released by the condensation of x gram of steam at 100^@C into water at 100^@C can be used to convert y gram of ice at 0^@C into water at 100^@C . Then the ratio of y:x is nearly [Given L_l = 80 cal//gm and L_v= 540 cal//gm ]

In an energy recycling process, X g of steam at 100^(@)C becomes water at 100^(@)C which converts Y g of ice at 0^(@)C into water at 100^(@)C .

The increase in internal energy of 1 kg of water at 100^(@) C when it is converted into steam at the same temperature and 1 atm (100 kPa) will be : [The density of water and steam are 1000 kg//m^(3) "and" 0.6 kg//m^(3) respectively. The latent heat of vapourisation of water is 2.25xx10^(6) J//kg .]

The heat of combustion of ethane gas is -368 kcal mol^(-1) . Assuming that 60% of heat is useful, how many m^(3) of ethane measured at NTP must be burned to supply heat to convert 50 kg of water at 10^(@)C to steam at 100^(@)C ?

calculate the increase in internal energy of 1 kg of water at 100^(o)C when it is converted into steam at the same temperature and at 1atm (100 kPa). The density of water and steam are 1000 kg m^(-3) and 0.6 kg m^(-3) respectively. The latent heat of vaporization of water =2.25xx10^(6) J kg^(1) .

A hot solid of mass 60 g at 100^(@)C is placed in 150 g of water at 20^(@)C . The final steady temperature recorded is 25^(@)C . Calculate the specific heat capacity of the solid. [Specific heat capacity of water = 4200 kg^(-1)""^(@)C^(-1) ]

A carbot freezer takes heat from water at 0^(@)C inside it and rejects it to the room at a temperature of 27^(@)C . The latent heat of ice is 336xx10^(3)Jkg^(-1) . If 5kg of water at 0^(@)C is converted into ice at 0^(@)C by the freezer, then the energy consumed by the freezer is close to :

A container of negligible heat capacity contains 1kg of water. It is connected by a steel rod of length 10m and area of cross-section 10cm^(2) to a large steam chamber which is maintained at 100^(@)C . If initial temperature of water is 0^(@)C , find the time after which it beomes 50^(@)C . (Neglect heat capacity of steel rod and assume no loss of heat to surroundings) (use table 3.1 , take specific heat of water =4180 J//kg.^(@)C)
