How does a volume of gas vary with respect to the absolute temperature?
The volume of a gas is directly proportional to its absolute temperature. More specifically, for a fixed mass of gas at a constant pressure, the volume (V) is directly proportional to the absolute temperature (T). This is Charles’ Law. The volume is directly to the absolute temperature.

Describe specific volume? | Indicates the volume that each pound of a gas occupies. |
Why does an object weigh less on the moon than on earth? | The earth has stronger gravitational attraction forces than the moon. |
The specific volume is the reciprocal of the density of the material, which is the mass per unit volume: r = (1/v) = (m/V). The “Specific Gravity” of a substance is the ratio of its mass to that of an equal volume of water at the same temperature and pressure.
What are the two types of energy most frequently used in HVAC?
What are the two types of energy most frequently used or considered in this industry? Electrical and heat energy.
What is both liquid and solid?
Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously. Applying high pressures and temperatures to potassium – a simple metal – creates a state in which most of the element’s atoms form a solid lattice structure, the findings show.
What is the relation between pressure and absolute temperature of an ideal gas at constant volume?
Gay-Lussac’s law It states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.
Which term is best defined as a measure of the amount of space a substance occupies a mass b volume c density D weight?
Density is the measurement of the mass of a substance or object that is often studied in science. The volume and density of an object can be calculated using the water displacement method.
What do we call a physical substance that occupies space and has mass?
Matter is anything that occupies space and has mass.

Which of the following types of energy is most commonly used for home heating?
The most common type of fuel used to heat a home is natural gas. It’s used in about 60% of American homes (energy.gov). A natural gas furnace, sometimes generally called a “central heating system,” uses a blower motor and air ducts to distribute warm air that is released via registers/grills.
What kind of energy does the industry use?
Industry uses many energy sources. The U.S. industrial sector uses a variety of energy sources including. Natural gas. Petroleum, such as distillate and residual fuel oils and hydrocarbon gas liquids (HGLs) Electricity.
Which is the most used energy source in the world?
Oil has been historically the world’s most used energy source accounting for approximately 39% of the global energy consumption. Photo: courtesy of ArionEstar. Accounting for approximately 39% of the global energy consumption, oil has historically been the world’s most used energy source.
Which is an example of a form of energy?
1 Chemical energy. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. 2 Mechanical energy. Compressed springs and stretched rubber bands are examples of stored mechanical energy. 3 Nuclear energy. Large amounts of energy can be released when the nuclei are combined or split apart. 4 Gravitational energy.
Which is the largest consumer of energy in the United States?
Every industry uses energy, but three industries account for most of the total U.S. industrial sector energy consumption. The U.S. Energy Information Administration estimates that in 2019, the bulk chemical industry was the largest industrial consumer of energy followed by the refining industry and the mining industry.
