Why does steam at `100^@C` cause more harm to the skin than water at `100^@C` ?

One mole of water at 100^@ C is converted into steam at 100^@ C at a constant pressure of 1 atm. The change in entropy is ____________. (heat of vaporization of water at 100^@ C=540 cal/g)

Why do stable nuclei never have more protons than neutrons?

How much energy needs to be supplied to 150 g of water at 100^@C to convert it to steam at 100^@C . (L=540 cal/g)

60 g of ice at 0^@C is mixed with 60 g of steam at 100^@C . At thermal equilibrium, the mixture contains (Latent heat of steam and ice are 540 g^-1 and 80 cal g^-1 respectively, specific heat of water = 1cal g^-1^@C^-1 )

1 g of water at 100^@C is coverted into steam at the same temperature. If the volume of steam is 1671 cm^2 , find the change in the internal energy of the system. Latent heat of steam = 2256 Jg ^-1 . (1 atmosphere pressure = 1.013 xx 10^5 Nm^-2 )

A Thermally Insulated Pot Has 150 G Ice at Temperature 0°C. How Much Steam of 100°C Has to Be Mixed to It, So that Water of Temperature 50°C Will Be Obtained? Given : specific heat capacity of water, c = 1 cal/g °C Latent heat of vaporization of water = 540 cal/g Latent heat of melting of ice = 80 cal/g

How much heat will be required to convert 20g of water at 100⁰C into steam at 100⁰C ? (Specific latent heat of vaporization of water = 540 cal/g)

1 of a steam at 100^@C melts how much ice at 0^@C ? ( Latent heat of ice=80 cal/g and latent heat of steam =540 cal/g )
