Since you are not changing temperature and I assume that the pressure is 1 atmosphere then you are concerned only with the latent heat, the heat needed to change the phase from solid into a liquid.
The latent heat of fusion of ice is 334 E+3 Joules /kg
Q=m Cl
Q= 40 x 334 E+3 =
Q=13.36 E+6 Joules

mutually as ice melts from sturdy to (liquid) water it take in heat temperature yet don’t advance its temperature. subsequently, to transit section from sturdy to liquid, it desires means. This heat temperature is universal as latent heat temperature. For water it truly is 334 kJ/kg. as a result to soften ice at 0 C and atmospheric rigidity of 40 kg to water desires 334x40 = 13360kJ or 13360000 Joules of means
