The gauge pressure in your car tires is 2.50×105 N/m2 at a temperature of 35.0ºC when you drive it onto a ferry boat to Alaska. What is their gauge pressure later, when their temperature has dropped to – 40.0ºC ?

The gauge pressure in your car tires is 3.00 ✕ 105 N/m2 at a temperature of 35.0°C when you drive it onto a ship in Los Angeles to be sent to Alaska. What is their gauge pressure (in atm) later, when their temperature has dropped to  −42.0°C?  Assume the tires have not gained or lost any air. ____atm??

Suppose you have a closed rigid container of air at 20 Celsius on the surface of the Earth. We increase the temperature of the container to 77, leaving it closed, and read a pressure gauge attached to the container.  Initially the reading was 101 KPa (kilopascals, or 1000 N/m2).  What is the new reading? Give your answer in KPa.

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.

On a cool morning in Alaska, when the temperature is -10.0 °C, the car tire pressure is 32 psi. Under strenuous driving, the tire heats up to 40.0 °C. What pressure will the tire gauge now ? O 17.5 psi O 20.6 psi O 38.0 psi O 40.9 psi O 55.6 psi

A weather balloon is designed to expand to a maximum radius of 22 m at its working altitude, where the air pressure is 0.030 atm and the temperature is 200 K. If the balloon is filled at atmospheric pressure and 309 K, what is its radius at liftoff?
