•14 In the temperature range 310 K to 330 K, the pressure p of a certain nonideal gas is related to volume V and temperature T by p = (24.9 J/K) т? (0.00662 J/K?) How much work is done by the gas if its temperature is raised from 315 K to 325 K while the pressure is held constant?

A certain sandwich cookie contains 55 CC of nutritional energy. For what amount of time must you swim in order to work off three cookies if swimming consumes 510 C/hC/h AND Instead of swimming you decide to run for 40 min at a pace that works off 860 C/hC/h. How many cookies have you worked off?

The pressure change of a balloon varies according to the P=CV*1/3 equation (C = 100 kPa m and n= -1/3) Since the balloon is inflated with air at a temperature of 25 ° C from 1 m3 volume to 3 m3 volume at 25 ° C , (R air = 0.287 kJ / kg 'K) a) Find the mass (kg) of air in the final state. b) Find the work (kj) done by air. c) Show the work done on the P-v diagram.
