On a cold winter day, the outside temperature is –5.0 °C while the interior of a well-insulated garage is maintained at 20.0 °C by an electric heater. Assume the walls have a total area of 75 m2, a thickness of 0.15 m, and a thermal conductivity of 0.042 W/(m · C°). What is the cost to heat the garage for six hours at these temperatures if the cost of electricity is $ 0.11/kWh? Note: 1 kWh = 3.6 × 106...
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 80.0 g and a temperature of 0°C. The water (before the ice cube is added) has a mass of 660 g and an initial temperature of 20.0°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...
A cooler is a closed container in the shape of a cube, each side 0.5 m in length, and made of polystyrene foam with a thermal conductivity k = 0.010 W /m K. The foam is 5 millimeters thick on all sides. The cooler contains 40 kg of ice and the inside temperature is a constant 0◦C. If the temperature outside the cooler is a constant 25◦C, calculate the power P and the total energy Q conducted through the cooler...
