The specific heat at constant volume is 0.724 kJ/kg K,and the specific heat at constant pressure is 1020 J/kg K. The observed temperature rise is 146 K. Calculate the specific gas constant; R, the mass of gas present, and the increase of the internal energy of the gas.

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.)
What is the change in length of a 3.00mlong column of mercury if its temperature changes from 37.0C to 40.0C, assuming the mercury is unconstrained?
A gas follows on an isothermal curve, where p is the pressure, V is the volume, b is a constant, and c is a function of temperature. Show that a temperature scale under an isochoric process can be established with this gas and is identical to that of an ideal gas.
Under what circumstances would you expect a gas to behave significantly differently than predicted by the ideal gas law?
Calculate the rate of heat conduction out of the human body, assuming that the core internal temperature is 37.0 , the skin temperature is 34.0 , the thickness of the fatty tissues between the core and the skin averages 1.00 cm, and the surface area is 1.40 m2.
The specific heat of substance A is greater than that of substance B. Both A and B are at the same initial temperature when equal amounts of energy are added to them. Assuming no melting or vaporization occurs, which of the following can be concluded about the final temperature TA of substance A and the final temperature TB of substance B? (a) TA TB (b) TA TB (c) TA = TB (d) More information is needed.
Most automobiles have a coolant reservoir to catch radiator fluid than may overflow when 1he engine is hot. A radiator is made of copper and is filled to its 16.0L capacity when at 10.0C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0C operating temperature, given that the fluid’s volume coefficient of expansion is =400106/C ? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95.0C.
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.
The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it To see just how rapidly the windows transfer heat by conduction, calculate the rate of conduction in watts through a 3.00-m2 window that is 0.634 cm thick (1/4 in.) if the temperatures of the inner and outer surfaces are 5.00 and 10.0 , respectively. (This rapid rate will not be maintained—the inner surface will cool, even to the point of frost formation.)
What are the main methods of heat transfer front the hot core of Earth to its surface? From Earth's surface to outer space? When our bodies get too warm, they respond by sweating and increasing blood circulation to the surface to transfer thermal energy away from the care. What effect will this have on a person in at 40.0C hot tub? Figure 14.30 shows a cutaway drawing of a thermos battle (also known as a Dewar flask), which is a device designed specifically to slow down all terms at heat transfer. Explain the functions of the various parts, such as the vacuum, the silvering of the walls, the thin-walled long glass neck, the rubber support, the air layer, and the stopper. Figure 14.30 The construction of a thermos bottle is designed to inhibit all methods of heat transfer.
A construction worker uses a steel tape to measure the length of an aluminum support column. If the measured length is 18.700 m when the temperature is 21.2C, what is the measured length when the temperature rises to 29.4C? Note: Dont neglect the expansion of the tape.
