What variable is volume?
Independent VariableIndependent Variable is the volume of the object. Dependent Variable is the mass of the object. Control Variables are the material of the object, room temperature, and temperature of the water.
What unit is volume measured in?
cubic unitsVolume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units. The SI unit of volume is the cubic meter (m3), which is a derived unit.
What is used to measure gas?
gas meter, device for measuring the quantity or rate of flow of a gas. Types of gas meters (by operating principles) include displacement, velocity, head, thermal, acoustic, and tracer. An example of the displacement principle is the bellows-and-diaphragm gas meter (shown in the diagram).

What variables and units are used to describe gasses?
Amount of gas (n): Typically measured in moles. Volume: In a closed system, the volume of the gas is the same as the volume of the container. Typically measured in liters. Pressure in a closed system: Typically measured in pascals (Pa) or atmospheres (atm).
Is the volume of a gas fixed or variable?
Gas is a state of matter that has no fixed shape and no fixed volume.
What is the state variable of gas?
Every equilibrium state of a thermodynamic system can be described by specific values of macroscopic variables. These variables are also called state variables. The equilibrium of a gas can be described by its pressure, temperature, volume, and mass.
What are the variables in Boyle's law?
The variables involved in Boyle's law are pressure, volume, number of moles and temperature.
Is gas measured in kg?
- Liquefied Petroleum Gas - 1 Litre contains 0.500 Kilograms. 1 Kilogram is contained in 2 Litres. - Liquefied Natural Gas - 1 litre contains 0.592 Kilograms. 1 Kilogram contains 1.689 litres.
Why is gas measured in kg?
LPG gas measurement is in a kg gas unit because the volume and pressure can be affected by temperature. LPG (propane) expands at 1.5% per 5.55°C temperature increase. In other words, the density changes.
Is gas measured in moles?
The molar volume of a gas is the volume of one mole of the gas at a given temperature and pressure. At STP, one mole (6.02 × 1023 representative particles) of any gas occupies a volume of 22.4 L (Figure below). Any gas occupies 22.4 L at standard temperature and pressure (0°C and 1 atm).
What is the difference between Therms, CCF, and MCF?
What are Therms, CCF, and MCF? They are all units of measure used by natural gas companies to determine how much gas you used, and therefore how much to bill you.
What is the natural gas measurement MCF? - Answers
MCF is a measure of volume of natural gas. One MCF equals one thousand (1,000) cubic feet of natural gas. M stands for the Roman numeral 1,000 C stands for cubic F stands for feet

How is the value of gas produced from the reserves determined?
The value of gas produced from the reserves is determined by its energy content , which is measured in joules. 4.2 Joules is approximately equivalent to the heat needed to increase the temperature of one gram of water at a standard pressure by 1 degree Celsius.
What are the properties of gas?
Some of the gas properties that may be measured include liquid volume, vapor pressure, or mass. The properties are affected by purity, temperature, and pressure. The value of gas produced from the reserves is determined by its energy ...
What is BTU in accounting?
Accounting in MCF. BTU is another unit of natural gas measurement that succeeded MCF due to OPEC’s actions. The federal government used it as a pricing structure. Nevertheless, following the expansion of the gas-liquid processing activities, the BTU became ineffective in reflecting the economic value of natural gas.

A BTU is the amount of heat required to raise one pound of water (approximately a pint), one degree Farenheit at or close to its point of maximum density.
How to find BTU per pound?
To find out the BTU's per pound, divide your therm into 100,000 BTU's (100 cubic feet or 1 standard therm). To find the number of BTU's per GGE, multiply the result by 5.66 (1 standard GGE). For example, if the therm of your area is 4.96 lbs, divide that number into 100,000 and you have the resulting BTU's per lb. of 20,161.29.
