The document discusses latent heat and specific heat capacity, specifically calculating the energy required to melt 450g of ice and to raise the temperature of 0.15kg of water from 20°C to 55°C. It uses the formula q=mcΔt to determine that 21,976.5 joules (or 22 kJ) are needed to heat the water. The calculations illustrate the concepts of heat transfer in materials.
