Thermal regulation of a room involves heating and cooling. If a newly constructed room in a house has a volume of 15400 L and a temperature of 5.0°C, what quantity of heat is required to raise the temperature of the room to the WHO recommended room temperature of 18°C?  Take the specific heat capacity of air to be 1020 J/kg•K and the mass of 1.0L of air to be 1.3 × 10^-3 kg.

A 2.0 kg iron ball is released from a 48.0 m tall building. The ball remains intact upon hitting the ground. If all the ball's mechanical energy is converted into heat energy of the ball, determine the rise in temperature of the ball.

A 3.0 kW electric heater is used to heat a copper pot filled with water which is initially at a temperature of 30°C. It takes 4 minutes for the water to reach the boiling point. If the mass of only the copper pot is 1 kg, Determine the volume of water, in cm³, that was present in the copper pot.

While racing, two RC bikes lose control and collide head-on, each traveling at 35 km/h. Following the impact, their kinetic energy is converted into thermal energy. Determine the rise in temperature for each RC bike, considering that their specific heat is similar to that of plastic,  which is approximately 2.1 J/g°C.

A water pump impeller can be considered to stir the water in an isolated system. Calculate heat absorbed by 2.0L of water when its temperature rises from 18°C to 60°C if no net flow of water occurs.
