What is the minimum velocity of a lead bullet if it completely melts when it strikes a wall? The initial temperature of the bullet is 127 °C and the melting point of lead is 327 °C. Assume all the thermal energy produced by the impact is absorbed by the bullet. (Take Clead %3D128 J/kg °C, L=23 kJ/kg)

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.
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.
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.
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?
A cylinder of volume 50.0 cm3 made of Pyrex glass is full to the brim with acetone. If the cylinder and acetone are warmed by 30.0C, (a) what is the change in volume of the glass? (b) Of the acetone? (c) Will any acetone spill out of the cylinder? (See Section 10.3.)
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.
An underground gasoline tank can hold 1.00 103 gallons of gasoline at 52.0F. If the tank is being filled on a day when the outdoor temperature (and the gasoline in a tanker truck) is 95.0F, how many gallons from the truck can be poured into the tank? Assume the temperature of the gasoline quickly cools from 95.0F to 52.0F upon entering the tank.
- (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?
How much stress is cleated in a steel beam if its temperature changes from 15 to 40 but it cannot expand? For steel, the Young's modulus Y=210109N/m2 from Stress, Strain, and Elastic Modulus (http://cnx.org/content/m58342/latest/#fs-id1163713086230). (Ignore the change in area resulting from the expansion.)
The concrete sections of a certain superhighway are designed to have a length of 25.0 m. The sections are poured and cured at 10.0C. What minimum spacing should the engineer leave between the sections to eliminate buckling if the concrete is to reach a temperature of 50.0C?
How is heat transfer related to temperature?
