How much heat is required to convert $1 \mathrm{kg}$ of ice at $0 °\mathrm{C}$ to water at $0 °\mathrm{C}$? (Latent heat of ice$=3.34\times {10}^3 \mathrm{J}/\mathrm{kg}$).

What will be the thermal capacity of vessel of mass $20 \mathrm{kg}$ and specific heat $450 \mathrm{J}/\mathrm{kg}/°\mathrm{C}$?

When $500 \mathrm{g}$ of boiling water is poured into a mug which weighs $0.15 \mathrm{kg}$, the temperature of the water falls to $70 °\mathrm{C}$, if the specific heat capacity of the substance of the mug is $800 \mathrm{J}/\mathrm{kg} °\mathrm{C}$, then the amount of heat lost by the water will be
