Definition: gas laws from The Macquarie Dictionary
1.

laws, especially Boyle's law and Charles's law, which relate the pressure, volume, and temperature of a gas. The combined ideal gas law states that for 1 mole of an ideal gas the product of the pressure and the volume is equal to the product of the absolute temperature and a constant known as the molar gas constant.


gas laws

From The Columbia Encyclopedia
physical laws describing the behavior of a gas under various conditions of pressure, volume, and temperature. Experimental results indicate that all real gases behave in approximately the same manner, having their volume reduced by about the same proportion of the original volume for each drop of 1° on the Celsius temperature scale . Graphs drawn to describe this behavior can be extrapolated, and all converge to a point corresponding to about −273 degrees Celsius (−459 degrees Fahrenheit)—this point is called absolute zero . A temperature scale defined so that zero degrees corresponds to this zero-volume temperature coordinate is known as an absolute scale. The Kelvin temperature scale begins at this absolute zero and has degrees the same size as those of the Celsius scale. The simplest gas laws relate pressure, volume, and temperature in pairs. Boyle's law (advanced by Robert Boyle in 1662) states that the pressure and volume of a gas are inversely proportional to one another, or PV = …

From Britannica Concise Encyclopedia
Laws that relate the pressure , volume, and temperature of a gas . Boyle’s law—named for Robert Boyle —states that, at constant temperature, the pressure P of a gas varies inversely with its volume V , or P V = k , where k is a constant. Charles’s law—named for J.-A.-C. Charles (1746–1823)—states…

From Gale Encyclopedia of Nursing and Allied Health
The gas laws are mathematical formulations of the interrelationships among the four variables that describe the behavior of a gas sample: its volume ( V ), pressure ( P ), temperature ( T ), and the amount ( n ) of gas present (see Gases, properties of). The properties of gases were already being…

From The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide
Physical laws concerning the behaviour of gases. They include Boyle's law and Charles's law , which are concerned with the relationships between the pressure (P), temperature (T), and volume (V) of an ideal (hypothetical) gas. These two laws can be combined to give the general or universal gas law , …

From The Hutchinson Unabridged Encyclopedia with Atlas and Weather Guide
Full answer The gas laws To find a combined gas law we need to look at the three individual gas equations. Boyle's Law This law states that:If a fixed mass of gas is at constant temperature, its volume ( V ) is inversely proportional to its pressure ( P ). PV = constant Charles's Law This law states…
