How much heat is requied ot convert 5 g ice at `-5^@C` into steam at `500^@C` under normal pressure?

Find the amount of heat required to convert 10 g ice at -10^@C into steam at 300^@C .

Find the amount of heat required to convert 1g ice at 0^@ C into steam at 100^@ C .

Photons absorbed in matter are converted to heat. A source emitting n photon/sec of frequency v is used to convert 1 kg of ice at 0^@C to water at 0^@C . Then, the time t taken for the conversion.

The heat of combustion of ethane gas is 373 K Cal per mole. Assuming that 50% of heat is lost, how many litres of ethane measured at S.T.P. must be burnt to convert 50 kg of water at 10^@C to steam at 100^@C ? One mole of gas occupies 22.4 litres at S.T.P. Latent heat (L) of steam = 2.25 xx 10^6 J k^-1 .

How much heat will be drawn from 5g steam at 200^@C to convert it into ice at -5^@C ?

How many calories of heat are required to compltely evaporate 1 g of ice at 0^@C ?

How will you convert : C_2H_5Cl + KCN to

A heating coil is immersed in a 100 g sample of H_(2)O (l) at a 1 atm and 100^(@) C in a closed vessel. In this heating process , 60% of the liquid is converted to the gaseous form at constant pressure of 1 atm . The densities of liquid and gas under these conditions are 1000 kg//m^(3) and 0.60 kg//m^(3) respectively . Magnitude of the work done forthe process is : (Take : 1L-atm= 100J)

How will you convert : C_2H_5Br + KNO_2 (aq) to
