Pressure, volume and temperature, and moles of gas are the four principal variables to describe a gas (for example, see related questions on Ideal Gas Law and others). The standard units are: Pressure: atmospheres (atm) Volume: liters (L) Temperature: Kelvin (K) Number of moles are measure in, well, moles.

Variables used to describe a gas include pressure (P), volume (V), temperature (T), and number of moles (n). Pressure is typically measured in atmospheres (atm) or Pascals (Pa), volume in liters (L) or cubic meters (m^3), temperature in Kelvin (K), and amount of substance in moles.

What is the importance of your choice of units in expressing the value of the ideal gas law constant?
If any other units are used, the value will be different. --Depending on the units you chose the value of the constant differs
What is the term used to describe the phase change of a liquid to gas?
The phase change from a liquid to a gas is called evaporation.
What can you measure in units of Pascal Torr or Bar?
Units of Pascal, Torr, or Bar are commonly used to measure pressure. These units represent the force exerted by a fluid or gas over a given area. Pascal is the SI unit, Torr is commonly used in vacuum measurements, and Bar is used in meteorology and industrial applications.
Will a balloon lift a notebook?
This depends on many variables. What is the weight of the notebook, what is the diameter of the balloon, what material is used for the balloon, what gas is used to fill the balloon, what is the weight of the material that is attached to the balloon and the notebook, is this taking place in earth's atmosphere, or somewhere else. There are several other minor variables, as well. And do remember, the balloon must be filled with a gas that is lighter than the surrounding medium!
What term is used for heat transfer because of te movement of a gas?
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
What word is used to describe the cycle of hot and cold gas?
The word to describe the cycle of hot and cold gas is convection.
What are units used to express the volume of gas?
The most common units used to express the volume of gas are liters (L) and cubic meters (m³). Other units such as milliliters (mL) and cubic centimeters (cm³) are also used for smaller volumes.
What units are used to measure gas?
Moles or (sometimes) grams.
Can an experiment that has sveral variables be used to explain a theory?
Yes. A good example of which is the Ideal Gas Law. PV=nRT You have four variables and one constant.
Which oil can use 410 a gas used ac units?
mineral oil
The word used to describe the cycle of hot and cold gas?
convection
Describe how different fluids are used to operate a can of spray paint?
gas is compressed in a spray can.
What is the importance of your choice of units in expressing the value of the ideal gas law constant?
If any other units are used, the value will be different. --Depending on the units you chose the value of the constant differs
How many gas units in 47 kg?
There are approximately 945 standard gas units in 47 kg.
How many Quarts are in 12 centimeters?
"Quart" is a unit of volume, whereas "centimeter" is a unit of length. Since these units are used to describe quantities with different physical dimensions, they can't be converted. If units of volume and length could be converted to each other, then you'd be able to figure out how many pints your car gets on a yard of gas.
What units are usually used to measure the volume of a gas?
Volume, Tempature, Pressure
Is argon a medical or industrial use?
Argon is an inert gas, and is often used as the fill gas between panes of glass in modern insulated window units. It is also used extensively as a shielding gas in welding operations.
