Aheating system musty maintain the interior of a building at 20 degree c during a period when the outside air temperature is 5 degree c and the heat transfer from the building through its roof and walls is 3 x 10^8 kj. for this duty heat pumps are under consideration that would operate between the dwelling and (a) the ground at 15 degree c . (b) a pond at 10 degree c. (c) the outside air at 5 degree c.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
