Consider Argon at 500 K and 500 kPa inside a rigid tank. The surrounding pressure is 100 kPa. Determine the specific volume. Report you answer based on units of m^3 /kg. Report your answer to three significant digits. However, do not include units in your answer.

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
