Text: The coefficients of expansion of all gases are the same, under all pressures and at all temperatures. The value of the coefficient is 1/273 = 0.00366. A cubic foot of gas at 0° C., when heated 1°, will become 1 + 0.00366 cubic feet. When heated to t°, it becomes 1 + 0.00366 t cubic feet. If t is 100°, the mass of gas which would have 1 cubic foot of volume at 0°, would become 1.366. In like manner, 1 cubic inch at 0° would expand to 1.366 cubic inches at 100°. If the Fahrenheit degree is used, the coefficient of expansion becomes 5/9 X 1/273 = 1/490. A quantity of gas heated from 0° to 273° C. would double in volume, if the pressure remained unchanged.
