Awell-insulated rigid tank is divided into two regions by a movable partition through which heat can flow via conduction. in the left region air exists with the following properties (2 kg, 5 bar, 350 k). in the right region co exists with the following properties (4 kg, 2 bar, 450 k). a pin holds the partition in place. the pin is removed and the air and co achieve pressure and temperature equilibrium. use a control volume that includes the air, the co and the partition. neglect the mass of the partition. a. assume constant specific heat for both air and co. look up the necessary specific heat values at an estimated average temperature of 400 k. b. determine the final temperature. c. using a new, more accurate, average air temperature and a new, more accurate, average co temperature, estimate how far off, in percent, the original specific heat estimates at 400 k are.

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

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
