You’re a lawyer with an unusual case. A whipped-cream can burst at a wedding, damaging the groom’s expensive tuxedo. The can warned against temperatures in excess of 50°C, and the manufacturer has evidence that it reached 60°C. You don’t contest this, but you point out that the can was only half full of cream when it burst, meaning that the gas propellant had available more than twice the volume it would in a full can, and that some of the propellant had already been used. You argue that the real safety criterion is pressure, and that the can’s maximum pressure wasn’t exceeded. Who’s right?

- In a chemical processing plant, a reaction chamber of fixed volume V0 is connected to a reservoir chamber of fixed volume 4V0 by a passage containing a thermally insulating porous plug. The plug permits the chambers to be at different temperatures. The plug allows gas to pass from either chamber to the other, ensuring that the pressure is the same in both. At one point in the processing, both chambers contain gas at a pressure of 1.00 atm and a temperature of 27.0C. Intake and exhaust valves to the pair of chambers are closed. The reservoir is maintained at 27.0C while the reaction chamber is heated to 400C. What is the pressure in both chambers after that is done?arrow_forwardA bicycle tire contains 2.00 L of gas at an absolute pressure of 7.00 × 105 N/m2 and a temperature of 18.0 °C . What will its pressure be if you let out an amount of air that has a volume of 100 cm3 at atmospheric pressure? Assume tire temperature and volume remain constant.arrow_forwardYou buy an "airtight" bag of potato chips packaged at sea level, and take the chips on an airplane flight. When you take the potato chips out of your "carry-on" bag, you notice it has noticeably "puffed up." Airplane cabins are typically pressurized at 0.87 atm, and assuming the temperature inside an airplane is about the same as inside a potato chip processing plant, by what percentage has the bag "puffed up" in comparison to when it was packaged?arrow_forward
- If I have an unknown quantity of gas held at a temperature of 365 K in a container with a volume of 25.9 L and a pressure of 8.5 atm, how many moles of gas do I have?arrow_forwardA motor car tyre has a pressure of 2 atmospheres at the room temperature of 27 degree C . If the tyre suddenly bursts, find the resulting temperature (y=1.4).arrow_forwardsketch, that calculates the pressure of a container of gas whose temperature increases from X Kelvin to 500 Kelvin, and the pressure if that container then increases to four times its original volume.x= 534.9arrow_forward
- In a shooting range, a soldier fired his rifle. If the barrel of the rifle is 58 cm long and has an opening of 275 mm, what is the average pressure of the expanding gas that propelled the 260-mg bullet? Ignore friction and assume that the speed of the bullet after passing through the length of the barrel is 375 m/s.arrow_forwardIn an ultrahigh vacuum system (with typical pressures lower than 10-7 pascal), the pressure is measured to be 1.00 x 10-10 torr (where 1 torr = 133 Pa). Assuming the temperature is 310 K, find the number of molecules in a volume of 1.00 m3.arrow_forwardAssuming a total pressure of 9.5 X 105 Pa, what is the partial pressure of each component in the mixture of 98% helium and 2.0% oxygen breathed by deep-sea divers? How does the partial pressure of oxygen in diving gas compare with its partial pressure in normal air?arrow_forward
- Item at position 1 At the same pressure, the ideal gas law is density x temperature = constant. An old house has only one thermostat upstairs set at 20 deg C. The air density upstairs is 1.2 kg/m3, while downstairs is 3% denser. The air temperature downstairs is _____ °C.arrow_forwardA helium filled weather balloon has a volume of 3.0 m3 at lift off where the air pressure is 1 atm and the temperature is 20oC. When airborne the temperature is -60oC and its volume expands to 120 m3. What is the pressure at the airborne location? 0.0058 atm 0.0083 atm 0.018 atm 0.034 atmarrow_forwardWhich contains the most moles: 10 g of hydrogen gas, 100 g of carbon, or 500 g of lead?arrow_forward
