Explanation Given info: The mass of water is 150 g , the thermal energy added to water at the rate of 55 J / s and time taken to add the thermal energy is 2.5 min . Formula to calculate the rate of thermal energy added in water is, P = Q t Here, Q is the heat energy added to the water. t is time taken for the heat energy. Rearrange the equation for Q , Q = P t (1) Substitute 55 J / s for P and 2.5 min for t in equation (1). Q = ( 55 J / s ) ( 2.5 min ) ( 60 s 1 min ) = 8250 J Thus, the heat energy added in water is 8250 J . Formula to calculate the heat absorbed by the water is, Q = m c Δ T Rearrange the equation for temperature T . Δ T = Q m c (2) m is the mass of the water

The iceberg requires 7.4 x 1020 Joules of energy to melt it completely. It absorbs energy from the Sun at a constant average rate of 88 Watts/m2. The total surface area of iceberg exposed to the sunlight is 12 billion (1.2 x 1010) square meters. How long will it take for sunlight to melt the entire iceberg in years

1.0 kg block of ice to melt in the kitchen. The temperature in the kitchen is 31 °C. The ice starts out at 0 °C and takes an hour to melt and reach the same temperature as the surrounding room (31 °C). How much heat does the 1.0 kg of ice/water absorb from the room as it melts and heats up to 31 °C in Joules absorbed? Latent heat of fusion for water/ice is 334,000 J/kg Specific heat of water is 4186 J/kg°C
