K (Kelvin)
When using the ideal gas law, the temperature measurement should be in Kelvin. This is because the ideal gas law requires an absolute temperature scale for accurate calculations, and Kelvin is an absolute temperature scale where 0 K represents absolute zero.
The ideal gas law, also known as the equation of state for an ideal gas, relates the pressure, volume, and temperature of an ideal gas if the volume is kept constant. This law states that when the temperature of an ideal gas increases at constant volume, the pressure of the gas will also increase.
An ideal gas conforming to the ideal gas law (PV = nRT) would behave at all conditions of temperature and pressure. However, in reality, no gas perfectly conforms to the gas laws under all conditions.
The ideal gas law is: PV = nRT, where P = pressure, V = volume, n= number of moles, R = ideal gas constant, T = Temperature in K.
CO2 can behave like an ideal gas, but is not an ideal gas. Depending on the temperature and amount of pressure applied, virtually all gasses can behave as ideal gasses. The ideal gas equation can be used on CO2 as a good approximation. (P = nRT/(V-nb) - an^2/V^2)
The Kelvin scale is used.
The ideal gas equation should be used with the Kelvin temperature scale because it is an absolute temperature scale where 0 K represents absolute zero. Using Celsius or Fahrenheit scales could lead to incorrect calculations in the ideal gas equation.

No, the ideal gas equation can be used with any temperature scale (e.g., Kelvin or Fahrenheit) as long as the proper gas constant is used in the calculations. The relationship between temperature scales can easily be accounted for in the ideal gas equation by using the appropriate conversion factors.
When using the ideal gas law, the temperature measurement should be in Kelvin. This is because the ideal gas law requires an absolute temperature scale for accurate calculations, and Kelvin is an absolute temperature scale where 0 K represents absolute zero.
The temperature scale that must be used in all gas laws is the Kelvin scale. This is because the Kelvin scale starts at absolute zero, which is the point where particles have minimal kinetic energy, making it the ideal scale for gas laws calculations.
The temperature scale used with Charles' law is the Kelvin scale. Charles' law states that the volume of a gas is directly proportional to its absolute temperature in Kelvin, when pressure and amount of gas are held constant.
Kelvin has the advantage that it is an absolute temperature scale - it starts from absolute zero. This simplifies several calculations; for example, in an ideal gas, at constant pressure, the volume of the gas is proportional to the absolute temperature. Similarly, calculations related to heat machines are simpler if an absolute temperature scale is used.
The ideal gas equation will give correct values as long as the temperature is expressed in an appropriate temperature scale (such as Kelvin or Rankine) to maintain a consistent relationship with the other variables involved (pressure, volume, and number of moles). Expressing temperature in degrees Celsius or Fahrenheit will not give accurate results with the ideal gas equation.
Charles' Law and other observations of gases are incorporated into the Ideal Gas Law. The Ideal Gas Law states that in an ideal gas the relationship between pressure, volume, temperature, and mass as PV = nRT, where P is pressure, V is volume, n is the number of moles (a measure of mass), R is the gas constant, and T is temperature. While this law specifically applies to ideal gases, most gases approximate the Ideal Gas Law under most conditions. Of particular note is the inclusion of density (mass and volume) and temperature, indicating a relationship between these three properties.The relationship between the pressure, volume, temperature, and amount of a gas ~APEX
The internal energy of an ideal gas is directly related to its temperature. As the temperature of an ideal gas increases, its internal energy also increases. This relationship is described by the equation for the internal energy of an ideal gas, which is proportional to the temperature of the gas.
Celsius is not used in gas laws because the temperature scale used is always in Kelvin. This is because Kelvin is an absolute temperature scale where zero represents the absence of thermal energy (absolute zero). This is necessary in gas laws to ensure accurate calculations and consistency.
