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`?

The heat of combustion of ethane gas is 368 kcal //mol . Assuming that 60% of the heat is useful, how many m^(3) of ethane 9 measured at STP ) must be burnt to supply enough heat to convert 50kg of water at 10^(@)C to steam at 100^(@)C ? Specific heat of water is 1 cal//g . Heat of vaporisation of H_(2)O is 540cal//g .

The heat of combustion of ethane gas is 368xx10^(3) cal mol^(-1) . If 62 per cent of heat is useful, how many m^(3) of ethane measured at STP must be burnt to supply enough heat to convert 50kg of water at 10^(@)C to steam at 100^(@)C ? Specific heat and heat of vaporisation of water are 1 cal //g and 540 cal//g respectively.

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 .

The heat of combustion of ethane gas at 373 k cal per mole. Assume that 50% of heat is lost, how many litres of ethane measured at STP must be convert 50 kg of water at 10^(@)C to steam at 100^(@)C ? One mole of gas oc cupies 22.4 litres at STP. Take latent heat of steam =2.25xx10^(6) j kg^(-1) .

How much heat is required to convert 5 kg of ice at -10°C into steam at 100°C?

The heat of combustion of ethane gas at 373 k cal per mole. Assume that 50% of heat is useful, how many be burnt litres to convert 60 kg of water at 20^(@)C to steam at 100^(@)C ? One mole of gas oc cupies 22.4 litre at S.T.P. Latent heat of steam = 2.25 xx 10^(6) Jkg^(-1) .
