What is temperature?

  • Temperature is a unit of measurement that can be expressed on a variety of scales, including Fahrenheit and Celsius.
  • Temperature shows the direction of the spontaneous movement of heat energy, i.e., from a hotter body (one with a higher temperature) to a colder body (one at a lower temperature).

If I know starting temp such as 0 degrees then I can say that it would take 7 hours as 7 * - 3 = -21.

If it is -3 degrees, then it would -3 *  8 =  -24 degrees.
