- Volume of ideal gas is increased from 2m^3 to 2 5m^3 while maintaining constant pressure of 3600psi. Calculate amount of work done by gas during expansion in J ?Why must a room air conditioner be placed in a window rather than just set on the floor and plugged in? Why can a refrigerator be set on the floor and plugged in?Explain why you can’t cool down your kitchen by leaving your refrigerator or freezer door open with your refrigerator plugged in for an extended period of time.
- A tire is in a room that has a constant pressure of 100kPa and constant temperature of 20°C. How many moles of air must be put into the tire for 20kJ of work to be done on the tire? (Round to whole number. No units, no decimal places. Example: 123.5 mol ---> 124)An ideal gas of 5 degrees of freedom expands isothermically at an initial pressure of 10 atm and at a temperature of -23 degrees Celsius from a volume of 25000 L to a volume of 75000L How many miles of gas are present ? What is the pressure after expansion? How much work was being done by the gas in this expansion?Why do frozen cans of soda often make the ends of the cans bulge outward or even burst? The chapters and topics based on these questions come from these concepts. (Phase Changes Thermodynamics.)
- Find the number of moles of gas for the mono atomic gas system. The temperate of the isotherm is 20.0 Celsius.An inventor claims to have invented an adiabaticsteady-flow device with a single inlet–outlet that produces230 kW when expanding 1 kg/s of air from 1200 kPa and300C to 100 kPa. Is this claim valid?
