\nThe amount of heat required to melt 100 g of ice at 0\u00b0C is 33360 J.
\n<\/section>\n
\n– The heat required for a substance to change phase (like melting) at a constant temperature is given by the formula Q = m * L, where Q is the heat energy, m is the mass, and L is the latent heat of fusion (for melting) or vaporization (for boiling).
\n– Given mass of ice m = 100 g.
\n– Given latent heat of melting of ice L = 333.6 J\/g.
\n– Heat required Q = 100 g * 333.6 J\/g = 33360 J.
\n<\/section>\n
\nLatent heat is the energy absorbed or released during a phase transition at constant temperature and pressure.
