Page 44 - Suppose a* = n, then x is called the logarithm ofnto the base a; thus the logarithm of a number to a given base is the index of the power to which the base must be raised to be equal to the number. The logarithm of n to the base a is written logaw; thus logaw = x expresses the same relation as a* = n.
Page 45 - The logarithm of any power of a number is equal to the logarithm of the number multiplied by the exponent of the power.
Page 55 - T the final absolute temperature ; let p' be the initial pressure, and p the final pressure; and let y(= 1.4) be the ratio of the specific heat of the gas at constant pressure to its specific heat at constant volume.
Page 44 - The logarithm of a product is equal to the sum of the logarithms of its factors.
Page 54 - The pressure of a given mass of gas at constant temperature is inversely proportional to its volume.
