A balloon contains 7 × 10-3 m3 of argon gas. The initial pressure and temperature are 1 atm and 290 K, respectively. The balloon is cooled until both its volume and pressure are halved. Find the final temperature (Tf).
An empty aerosol sprayer of volume 0.3 liters is filled with 0.3 g of carbon dioxide gas at a temperature of 25 °C. The molecular mass of carbon dioxide is 44 g/mol. Find the pressure (p) inside the sprayer. Express your answer i) in pascals and ii) in atmospheres.
A buoy has a gauge pressure of 32 psi when the temperature is 25°C. The buoy has a volume of 10 liters and contains pure helium gas. Due to a puncture, the gauge pressure drops to 25 psi on a day when the temperature is 20°C. What mass of helium gas leaked out of the buoy assuming the volume remains constant?
A helium spherical balloon is filled at sea level with a volume of 2.00 m³ at a temperature of 20.0°C. The balloon rises to an altitude where the pressure is 0.60 atm and the temperature is -10.0°C. What will be the new radius of the balloon at this altitude?
At some pressure and temperature, you have 0.025 m³ of gas in a vessel. To find the effect of compression on this gas, you exert a force that reduces its volume to 0.022 m³. This compression decreases the temperature of the gas by 7.0 K, and the pressure inside the vessel increases by 350 Pa. What was the initial temperature and pressure before this compression? [n = 4.0 mol]
In a deep-sea exploration vessel, a container holds 16.00 mol of nitrogen gas at a moderate temperature of 25.0°C and a gauge pressure of 0.500 atm. Determine (a) the volume occupied by the nitrogen gas in the vessel under these conditions and (b) predict the new temperature required if the gas is compressed to one-third of its original volume to withstand a deeper dive with a gauge pressure of 1.50 atm.
Imagine a colorful balloon floating gently in a bright blue sky on a clear day. This balloon, filled with 30 kg of helium gas (He), is at Standard Temperature and Pressure (STP). Your task is to determine the volume of this balloon filled with helium gas.
