Is PV NRT in Kelvin or Celsius?In SI units, p is measured in pascals, V is measured in cubic metres, n is measured in moles, and T in kelvins (the Kelvin scale is a shifted Celsius scale, where 0.00 K = −273.15 °C, the lowest possible temperature).
What is the temperature of PV NRT?A pressure of 1 atmosphere is 101325 Pa. The volume of 1 dm3 has to be converted to cubic metres, by dividing by 1000. We have a volume of 0.001 m3. The temperature is 293 K.
Is temperature in Kelvin for ideal gas law?The only constant about the constant is that the temperature scale in all is KELVIN. When using the Ideal Gas Law to calculate any property of a gas, you must match the units to the gas constant you choose to use and you always must place your temperature into Kelvin.
Why is Kelvin used in the ideal gas law?The Kelvin scale is used in gas law problems because the pressure and volume of a gas depend on the kinetic energy or motion of the particles. The Kelvin scale is proportional to the KE of the particles… that is, 0 K (absolute zero) means 0 kinetic energy.
