K vs C

Postby Ishita Monga 1B » Mon Jan 15, 2018 10:36 pm

Why are the units for temperature in heat capacity sometimes written in terms of kelvin and other times in celsius?

When you are solving for the change in temperature, it does not matter whether you use Kelvin or Celsius because you will get the same answer.

SO just to be sure because i had the same question concerning K vs C: you can use K and C interchangeably without affecting the answer?

If you are finding the difference from the final to the initial temperature, you can use C and K interchangeably because both will give the same difference. However, if you are using the ideal gas equation (PV=nRT) you want to make sure that your temperature is in K because using C instead of K will give a different answer.

In calculating temperature change, K and C can be used interchangeably because the temperature change will have the same magnitude in both units due to the conversion relation (linear translation - 273 is added to every Celsius temperature to get its Kelvin equivalent) between Kelvin and Celsius. In plugging in temperature into equations such as PV=nRT, it is important to note that the units for temperature in this case would be Kelvin and would need to be converted if necessary.

When you're calculating for the change in temperature, it doesn't matter what units of temperature it is in.
