Gasoline yields 4.8 ? 107 joules per kg when burned. The density of gasoline is approximately the same as that of water, and 1 gal = 3.8 L. How much energy does your car use on a trip of 100 mile if you get 25 mile per gallon?

A window glass 0.50-cm thick has dimensions of 3.0 m by 1.5 m. If the outside temperature is -10°C and the inside temperature 20°C, what is the rate of heat conduction through the window?

The thermal conductivity of aluminum is twice that of brass. Two rods (one aluminum and the other brass) are joined together end to end in excellent thermal contact. The rods are of equal lengths and radii. The free end of the brass rod is maintained at 0°C and the aluminum's free end is heated to 200°C. If no heat escapes from the sides of the rods, what is the temperature at the interface between the two metals?

A block of ice at 0eC is added to a 150-g aluminum calorimeter cup that holds 200 g of water at 100C. If all but 2.00 g of ice melt, what was the original mass of the block of ice?

The measure of the average kinetic energy of individual molecules is referred to as:
