4. - Calculate the temperature in degrees Fahrenheit for 45o C.
5. - At what temperature two thermometers graduated in degrees Celsius and Fahrenheit respectively, show the same number?
6. - One kilocalorie is equal to ________________________BTU.

- A copper container of 0.25-kg mass contains 0.4 kg of water. Container and water are initially at room temperature of 20o C as measured by a thermometer. A block of copper of 1-kg mass is heated to 100o C by placing in a steam from water boiling at normal atmospheric pressure. It is then removed from the steam and quickly placed in the water of the calorimeter. The copper block cools, the water container becomes warmer, and the final temperature as read on the thermometer, is found to be 34.5o
C. From these data determine the specific heat capacity of the copper.
9. - The heat can be transferred by ___________________,__________________, and ______________
10. - The rate of heat flow by conduction per unit area per unit temperature gradient is called
11. - The rate of heat flow for a piece of corkboard 20 ft2 area and 4 inches width, where the inside temperature is 60o F and the outside temperature is 95o F is
