On a nice winter day at the South Pole, the temperature rises to 60°F. What is the approximate temperature in degrees Celsius?
Give an example of a physical property that varies with temperature and describe how it is used to measure temperature.
Markings to indicate length are placed on a steel tape in a room that is at a temperature of 22C. Measurements are then made with the same tape on a day when the temperature is 27C. Are the measurements too long, too short, or accurate?
One easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose the house already had 15 cm of fiberglass insulation in the attic and in all the exterior surfaces. If you added an extra 8.0 cm of fiberglass to the attic, then by what percentage would the heating cost of the house drop? Take the single story house to be of dimensions 10 m by 15 m by 3.0 m. Ignore air infiltration and heat loss through windows and doors.
An electrician is wiring new electrical outlets in a house and has stored a 50.0-m length of copper wire outside where the temperature is 15.0C. When the wire is brought inside and warmed to 23.0C, by what amount in centimeters will the wires length increase due to the temperature change? (See Section 10.3.)
The Surface temperature of the Sun is about 5750 K. What is this temperature on the Fahrenheit scale?
- (a) Compute the amount of heat needed to raise the temperature of 1 kg of water from its freezing point to its normal boiling point. (b) How does your answer to (a) compare to the amount of heat needed to convert 1 kg of water at 100° C to steam at 100°C?
A Styrofoam box has a surface area of 0.80 m and a wall thickness of 2.0 cm. The temperature of the inner surface is 5.0C, and the outside temperature is 25C. If it takes 8.0 h for 5.0 kg of ice to melt in the container, determine the thermal conductivity of the Styrofoam.
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 copper rod and an aluminum rod of equal diameter are joined end to end in good thermal contact. The temperature of the free end of the copper rod is held constant at 100.C and that of the far end of the aluminum rod is held at 0C. If the copper rod is 0.15 m long, what must be the length of the aluminum rod so that the temperature at the junction is 50.C?
The temperature difference between the inside and the outside of a home on a cold winter day is 57.0F. Express this difference on (a) the (Celsius scale and (b) the Kelvin scale.
A Styrofoam box has a surface area of 0.80 m and a wall thickness of 2.0 cm. The temperature of the inner surface is 5.0C, and the outside temperature is 25C. If it takes 8.0 h for 5.0 kg of ice to melt in the container, determine the thermal conductivity of the Styrofoam.
