If I put the temperature is increasing would that be the same as going from -2.1 degrees Celsius to 100 degrees Celsius. OR would it be as the temperature is getting warmer??

If the temperature is increasing, it generally means that the temperature is getting warmer. In the context of your question, going from -2.1 degrees Celsius to 100 degrees Celsius would indeed be considered an increase in temperature. This represents a significant change from a cold temperature to a much warmer one.

To understand this concept, it's important to know that temperature is a measure of the average kinetic energy of the particles in a substance. As the average kinetic energy increases, the temperature rises, and the substance feels warmer.

In order to determine if the temperature is increasing or getting warmer, you can compare the initial and final temperatures. If the final temperature is higher than the initial temperature, then the temperature is indeed increasing and the substance is getting warmer. In the example you provided, the final temperature of 100 degrees Celsius is significantly higher than the initial temperature of -2.1 degrees Celsius, so the temperature is indeed getting warmer.
