A hollow aluminum cylinder 20.0 cm deep has an internal capacity of 2.000 L at 20.0C. It is completely filled with turpentine at 20.0C. The turpentine and the aluminum cylinder are then slowly warmed together to 80.0C. (a) How much turpentine overflows? (b) What is the volume of the turpentine remaining in the cylinder at 80.0C? (c) If the combination with this amount of turpentine is then cooled back to 20.0C, how far below the cylinders rim does the turpentines surface recede?

What is me Fahrenheit temperature of a person with at 39.0°C fever?

Late on an autumn day, the relative humidity is 45.0% and the temperature is 20.0C. What will the relative humidity be that evening when the temperature has dropped to 10.0C, assuming constant water vapor density?

If you place 0C ice into 0C water in an insulated container, what will happen? Will some ice melt, will more water freeze, or will neither take place?

For the human body, what is the rate of heat transfer by conduction through the body’s tissue with the following conditions: the tissue thickness is 3.00 cm, the change in temperature is 2.00C, and the skin area is 1.50m2. How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)

A large body of lava from a volcano has stopped flowing and is slowly cooling. The interior of the lava is at 1200C, its surface is at 450C, and the surroundings are at 27.0C. (a) Calculate the rate at which energy is transferred by radiation from 1.00m2 of surface lava into the surroundings, assuming the emissivity is 1.00. (b) Suppose heat conduction to the surface occurs at the same rate. What is the thickness of the lava between the 450C surface and the 1200C interior, assuming that the lava’s conductivity is the same as that of brick?

Calculate the rate of heat conduction out of the human body, assuming that the core internal temperature is 37.0C, the skin temperature is 34.0C, the thickness of the tissues between averages 1.00 cm, and the surface area is 1.40m2.

A 1.00-km steel railroad rail is fastened securely at both ends when the temperature is 20.0C. As the temperature increases, the rail buckles, taking the shape of an arc of a vertical circle. Find the height h of the center of the rail when the temperature is 25.0C. (You will need to solve a transcendental equation.)

What does it mean to say that two systems are in thermal equilibrium?
