In summary, To convert between Kelvin and Celsius temperatures, simply add or subtract 273.15 depending on the direction of conversion. A rigid container is used to compare the two scales to ensure accurate measurement. The size of a degree also differs between the two scales, with the zero point being absolute zero for Kelvin and the freezing point of water for Celsius. Comparing Kelvin and Celsius temperatures is significant for understanding temperature measurement and conversions. While they cannot be used interchangeably, they can be converted using a formula.

If you heat the air inside a rigid, sealed container until its Kelvin temperature doubles, the air pressure in the container will also double. Is the same thing true if you double the Celsius temperature of the air in the container?

I don't think so, because pressure is directly proportional to the Kelvin temperature and pressure is directly proportional to (273 + the Celsius temperature).
What do you think?

Correct. :smile:
 

1. How do you convert Kelvin to Celsius and vice versa?

To convert from Kelvin to Celsius, simply subtract 273.15 from the Kelvin temperature. To convert from Celsius to Kelvin, add 273.15 to the Celsius temperature.

2. Why is a rigid container used to compare Kelvin and Celsius temperatures?

A rigid container is used to compare Kelvin and Celsius temperatures because it ensures that the volume of the container remains constant, which is important for accurate temperature measurement.

3. Is there a difference in the size of a degree in Kelvin and Celsius?

Yes, there is a difference in the size of a degree in Kelvin and Celsius. One degree in Kelvin is equivalent to one degree Celsius, but the zero point on the Kelvin scale is absolute zero (-273.15°C), while the zero point on the Celsius scale is the freezing point of water (0°C).

4. What is the significance of comparing Kelvin and Celsius temperatures?

Comparing Kelvin and Celsius temperatures allows for a better understanding of temperature measurement and the relationship between the two scales. It also helps to convert between the two scales and make accurate temperature calculations.

5. Can Kelvin and Celsius temperatures be used interchangeably?

No, Kelvin and Celsius temperatures cannot be used interchangeably. They are two different temperature scales with different zero points and size of degrees. However, they can be converted to each other using a simple mathematical formula.
