Question

Celsius

The world's most common temperature scale is Celsius. Abbreviated C, it is virtually the same as the old centigrade scale and therefore has 100 degrees between the melting point and boiling point of water, taken to occur at 0 and 100 degrees, respectively.
Kelvin
Temperature is a measure of the thermal energy of a system. Thus cooling can proceed only to the point at which all of the thermal energy is removed from the system, and this process defines the temperature of absolute zero. The Kelvin scale, also called the absolute temerature scale, takes its zero to be absolute zero. It uses units of kelvins (abbreviated K), which are the same size as the degrees on the Celsius scale.
Fahrenheit This anachronistic temperature scale, used primarily in the United States, has zero defined as the lowest temperature that can be reached with ice and salt, and 100 degrees as the hottest daytime temperature observed in Italy by Torricelli.
Required:
A. In the equation of state for the perfect gas, pV = nRT , which of the following three temperature scales must be used?
O Celsius
O Kelvin
O Fahrenheit

Answer 1

In this equation the scale used must be Kelvin

Step-by-step explanation:

The absolute temperature is the value of the measured temperature relative to a scale starting at Absolute Zero (0 K or -273.15 °C). It is one of the main parameters used in thermodynamics and statistical mechanics. In the international system of units it is expressed in kelvin, whose symbol is K

The absolute temperature should always be used in the ideal gas state equation as this can only be in kelvin grade scale.
