A gas inside of a balloon is heated. As a result, its volume increases from 0.15 m3 to 0.4 m3. At the start of the process, pressure was 300 kPa. Throughout the process, the pressure and volume are related by PV1.2=constant. What is the boundary work done in the process?

A gas is compressed inside a compressor’s cylinder. Whenthe piston is at its bottom dead center, the gas is initiallyat 10 psig, 65°F, and 10.5 in3. After compression andwhen the piston is at top dead center, the gas is 180°Fand occupies 1.5 in3. What would be the new pressure ofthe gas in psig?

2. During an expansion process, the pressure of a gas changes from 90 to 800 kPa according to the relation P = aV + b, where a = 1000 kPa/m² and b is a constant. If the initial volume of the gas is 0.5 m', calculate the work done during this process.

Determine the work done by a kilogram of the fluid system as it expands slowly in a piston-cylinder arrangement from an initial pressure and volume of 550 kPa and 0.028 m3 respectively to a final volume of 0.113 m3in accordance with the following defining relations: a.) p = C; b.) pV = C; c.) pV1.4 = C; d.) p = -730V + 690 kpa where V is in m3

There is an 500g container made out of aluminum holding 300g of water. The Water and Aluminum have reached thermal equilibrium at 40 degrees Celsius. A 200g block of iron at a temperature of 0 degrees Celsius is later dropped into the water. Using the specific heat for water=4180J/kg/C. The specific heat for aluminum is 900 J/kg/C. The specific heat for iron is 450 J/kg/C. The final temperature of the three materials will be degrees celsius. The thermal energy of the water changes by Joules. (give an amount and include a + if it increases and a - if it decreases) The thermal energy of the aluminum changes by Joules. (give an amount and include a + if it increases and a - if it decreases) The thermal energy of the iron changes by Joules. (give an amount and unit and include a + if it increases and a - if the value decreases)

Q3: You have an ideal gas in an insulated container. You compress it from a pressure of 40 × 105 Pa to 20 × 105 Pa, while increasing the volume from 10 to 20 m3. What is the work you done by the gas a- 10 J b- 300 J c- 500 J d- 880 J

ft-lb 7. One pound of air R = 53.3 is compressed isothermally in a closed system from ib-R 15 psia and 80°F to 90 psia. Compute the heat transfer.

A system receives 42 kJ of heat while expanding with volume change of 0.123 m3 against an atmosphere of 12 N/cm2. A mass of 80 kg in the surroundings is also lifted through a distance of 6 metres. (i) Find the change in energy of the system. (ii) The system is returned to its initial volume by an adiabatic process which requires 100 kJ of work. Find the change in energy of system. (iii) Determine the total change in energy of the system.
