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 0.250kg aluminum bowl holding 0.800 kg of soup at 25.0C is placed in a freezer. What is the final temperature if 377 kJ of energy is transferred from the bowl and soup, assuming the soup's thermal properties are the same as that of water? Explicitly show how you follow the steps in ProblemSolving Strategies for the Effects of Heat Transfer.
The same heat transfer into identical masses of different substances produces different temperature changes. Calculate the final temperature when 1.00 kcal of heat transfers into 1.00 kg of the following, originally at 20.0C : (a) water; (b) concrete; (c) steel; and (d) mercury.
What three factors affect the heat transfer that is necessary to change an object's temperature?
Suppose you walk into a sauna that has an ambient temperature of 50.0C. (a) Calculate the rate of heat transfer to you by radiation given your skin temperature is 37.0C, the emissivity of skin is 0.98, and the surface area of your body is 1.50m2. (b) If all other forms of heat transfer are balanced (the net heat transfer is zero), at what rate will your body temperature increase if your mass is 75.0 kg?
Describe a situation in which heat transfer occurs. What are the resulting forms of energy?
Some gun fanciers make their own bullets, which involves melting and casting the lead slugs. How much heat transfer is needed to raise the temperature and melt 0.500 kg of lead, starting from 25.0C ?
Heat transfer can cause temperature and phase changes. What else can cause these changes?
How much heat transfer (in kilocalories) is required to thaw a 0.450kg package of frozen vegetables originally at if their heat of fusion is the same as that of water?
How does the latent heat of fusion of water help slow the decrease of air temperatures, perhaps preventing temperatures from falling significantly below 0C, in the vicinity of large bodies of water?
If you pour 0.0100 kg of 20.0C water onto a 1.20kg block of ice (which is initially at 15.0C ), what is the final temperature? You may assume that the water cools so rapidly that effects of the surroundings are negligible.
On a hot dry day, evaporation from a lake has just enough heat transfer to balance the 1.00kW/m2 of incoming heat from the Sun. What mass of water evaporates in 1.00 h from each square meter? Explicitly show how you follow the steps in the Problem-Solving Strategies for the Effects of Heat Transfer.
