A 1.50 kg block of ice initially at a temperature of 0 °C is placed inside an apparatus that allows 150 kJ of heat to flow into the ice. What mass of ice melts as a result? O 0.45 kg O 0.75 kg O 1.33 kg 2.23 kg O 1.00 kg

You drop an ice cube into an insulated container full of water and wait for the ice cube to completely melt. The ice cube initially has a mass of 60.0 g and a temperature of 0°C. The water (before the ice cube is added) has a mass of 850 g and an initial temperature of 30.0°C. What is the final temperature (in °C) of the mixture? (Assume no energy is lost to the walls of the container, or to the environment.)

How much thermal energy/heat is required to raise 2.3 kg of lead from 300°C to 1800°C? Use Table 1 p281 and Table 1 p291 to help you. O 1.8 x 10°J O 2. 5 x 10°J O8.2 x 10³J O4.5 x 10°J x 10°J

What is the rate of heat transfer in J/s through the body's skin and the fat layer just beneath its surface? Treat the skin and fat as a single layer that is 1.20 cm thick. Assume the temperature of the inner surface of the layer corresponds to internal body temperature, or 36.7 °C, and the temperature of the outer surface of the layer corresponds to skin temperature, or 34.0 °C. Take the total surface area of the layer to be 1.50 m² and use a value of 0.413 W/(m-C°) for the average thermal conductivity of the layer. Number Units
