When 1 gm of water changes from liquid to vapour phase at constant pressure of 1 atmosphre, the volume increases from 1cc to 1671cc. The heat of vaporisation at his pressure is 540 cal/gm. Increase in internal energy of water is (1 atmosphre =1.01x `10^(6)` dyne/`cm^(2)`)

When 1 gm of water changes from liquid to vapour phase at constant pressures of 1 atmosphere, the volume increases from 1 cc to 1671 cc. The heat of vaporisation at this pressure is 540 cal/gm. Increase in internal in internal energy of water is (1 atmosphere = 1.01xx10^(6) "dyne/cm"^(2))

1 g of H_(2)O changes from liquid to vapour phase at constant pressure at 1 atm . The pressure increases from 1 cc to 1671 cc . The heat of vaporization at this pressure is 540 cal//g . The increase in internal energy of water is

1g of water changes from liquid to vapour phase at constant pressure of 1 atmosphere, the volume increases from 1 mL to 1671 mL . The heat of vaporisation at this pressure is 540 cal//g . Find the: (a) Work done (in J )during phase change. (b) Increase in internal energy of water.

1 kg of water having a volume of 10^(-3) m ^(3) becomes 1.67 m^(3) of steam when boiled at a pressure of one atmosphere. The heat of vapourization at this pressure is 540 kcal/kg. Calculate the increase in internal energy and the work done in expansion.

One gram of water (1 cm^(3)) becomes 1671 cm^(3) of steam at a pressure of 1 atm. The latent heat of vaporization at this pressure is 2256 J/g. Calculate the external work and the increase in internal energy.

1 gm of water having a volume of 1 cc becomes. 1671 cc steam when boiled at atmospheric pressure. If latent heat of vapourization of water is 540cal//gm at 1 atm, how much gain in internal energy takes place ?

1 g of water (volume 1 cm^(3) becomes 1671 cm^(3) of steam when boiled at a pressure of 1atm. The latent heat of vaporisation is 540 cal/g, then the external work done is (1 atm = 1.013 xx 10^(5) N/ m^(2))

When a gas is heated its volume increases from 100 cc to 500cc, at a constant pressure of 1 atmospher. Calculate the heat needed for doing external work.
