In a sufficiently large pumped cylinder, closed by a piston, a little ice water is placed. Ice mass m, temperature 0°C, saturated water vapor pressure at 0°C is P₀. How much do you need to change the blocked volume with the help of a piston so that all the ice melts? What kind of work do you need to do? Specific heat of vaporization q, specific heat of ice melting λ, molecular weight of water µ.
