- A spherical balloon of volume 4.07 x 10³ cm³ contains helium at a pressure of 1.21 x 105 Pa. How many moles of helium are in the balloon if the average kinetic energy of the helium atoms is 3.60 x 10-2² J? mol(a) An ideal gas occupies a volume of 1.2 cm³ at 20°C and atmospheric pressure. Determine the number of molecules of gas in the container. molecules (b) If the pressure of the 1.2-cm³ volume is reduced to 2.2 x 10-11 Pa (an extremely good vacuum) while the temperature remains constant, how many moles of gas remain in the container? mol(a) How many molecules are present in a sample of an ideal gas that occupies a volume of 1.90 cm3, is at a temperature of 20°C, and is at atmospheric pressure? molecules (b) How many molecules of the gas are present if the volume and temperature are the same as in part (a), but the pressure is now 1.80 ✕ 10−11 Pa (an extremely good vacuum)? molecules
- There are 1.5 times as many molecules as Avogadro's number at a temperature of 2.1°C inside a sealed cube with dimensions 3.0 cm ✕ 3.0 cm ✕ 3.0 cm. How much force does the gas exert on one of the walls of the cube?On a chilly 10°C day, you quickly take a deep breath—all your lungs can hold, 4.0 L. The air warms to your body temperature of 37°C. If the air starts at a pressure of 1.0 atm, and you hold the volume of your lungs constant (a good approximation) and the number of molecules in your lungs stays constant aswell (also a good approximation), what is the increase in pressure inside your lungs?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?
