heating value of a fuel

Physics; Thermodynamics

The amount of heat released when a specified amount of fuel at room temperature is completely burned and the combustion products are cooled to the room temperature.

mixing chamber

Physics; Thermodynamics

The section of a control volume where mixing process for two or more streams of fluids takes place. The mixing chamber does not have to be a distinct chamber. Mixing chambers are ...

latent heat of vaporization

Physics; Thermodynamics

The amount of energy absorbed during vaporization which is equivalent to the energy released during condensation.

solid phase

Physics; Thermodynamics

A state in which molecules arranged in a three-dimensional pattern (lattice) that is repeated throughout. Because of the small distances between molecules in a solid, the ...

molar mass

Physics; Thermodynamics

Represented by the symbol M, molar mass is defined as the mass of one mole (also called a gram-mole) of a substance in grams, or the mass of one kmol (also called a kilogram-mole) ...

latent heat of fusion

Physics; Thermodynamics

The amount of energy absorbed during melting and is equivalent to the amount of energy released during freezing.

gas phase of a substance

Physics; Thermodynamics

The state of a substance in which molecules are far apart from each other with no specific molecular order. Gas molecules move about at random, continually colliding with each ...
