Gas Vocab
pressure varies inversely with ______ if temp is constant in Boyle's law
What is volume
If a hairspray can is heated, and the pressure inside the can increases until it explodes, which gas law was demonstrated?
What is Gay-Lussac's Law? (Volume of compressed gas inside a canister stays constant)
Volume varies directly with ____________ (constant pressure)
What is temperature
________ varies directly with temperature (constant volume)
Who is pressure
A sample of oxygen gas collected in the lab occupies a volume of 250. mL when its pressure is 720. mmHg. What volume will the gas occupy at a pressure of 760. mmHg if the temperature is held constant?
What is 237 mL
As we inhale, the rib cage expands, and the diaphragm moves downward, increasing the volume of the lungs and decreasing the gas pressure inside the lungs. Exhalation is the reverse process—the volume of the lungs decreases and the gas pressure increases, forcing air out of the lungs. Which gas law is demonstrated?
What is Boyle's Law
A sample of neon gas occupies a volume of 742 mL at 35˚C. What volume will the gas occupy at 60˚C if the pressure is held constant?
What is 802 mL
If volume is held constant, and pressure decreases, what happens to temperature?
What is decreases?
The amount of space something occupies.
What is volume?
As pressure increase what happens to volume if temperature is held constant
What is decreases
A common problem car owners may encounter is slightly deflated tires when the temperature begins to drop during the winter months. Which gas law is demonstrated?
What is Gay-Lussac's Law? (Volume in a car tire stays constant)
Increasing temperature will have what affect on volume if pressure is held constant.
What is increase
A sample of oxygen at 28.0°C has 340.0 kPa. What will its temperature be at 150.0 kPa?
132.8 K
All of these: 273 Kelvin or 0˚C and 1 atmosphere, 760 mmHg/torr, or 101.3 kPa.
Represent what?
What is STP (standard temperature and pressure)
A sample of gas is transferred from a 75 mL vessel to a 500.0 mL vessel. If the initial pressure of the gas is 145 atm and if the temperature is held constant, what is the pressure of the gas sample in the 500.0 mL vessel?
What is 21.75 atm
An empty water bottle is left in the fridge, and when the fridge is next opened, the bottled has been crushed. Which law applies?
What is Charles Law? (Pressure in a fridge stays constant)
Neon occupies a volume of 2.80 L at -35°C. What volume will it occupy at 43°C?
What is 3.7L
What is the pressure of a car tire that had an initial pressure of 1.8 atm but was heated from 38°C to 123°C?
2.3 atm
We use psi to measure most pressures in America. What does psi stand for?
What is 'pounds per square inch'
A gas of volume V is place in a balloon. The pressure is reduced to 1/5 of the original pressure. The volume will be _____ what it was originally.
What is 5 times
A deep sea fish rises to the surface and begins to bloat. Which gas law applies?
What is Boyle's Law
A sample of gas with a volume of 30.0 mL at 25.0oC is heated to 50.0oC. What is the new volume of the gas?
32.5 mL
