Heat is the kinetic energy of movement of atoms and molecules. This means that, if it could get cold enough, all such movement would stop and it would be impossible for it to get any colder. That temperature is known as Absolute Zero and is -459 degrees Fahrenheit or -273.15 degrees Celsius. The Kelvin scale, used in science, uses Celsius degrees but starts at Absolute Zero, instead of the freezing point of water.
It was cold here recently. Suppose that there is a frigid cold winter day, with a temperature of 0 Fahrenheit (-18 Celsius). Now suppose that there is a scorching hot summer day, with a temperature of 100 Fahrenheit (38 Celsius).
It might seem that there is many times the amount of heat on the hot day, as on the cold day. In the following diagram the blue line represents the cold day and the red line the hot day. Going by the total amount of heat, relative to Absolute Zero, there is actually 82% of the heat of the hot day on the cold day.
The reason it seems so different to us is that so much of our bodies are made of water, which is sensitive to temperature.
Here is a link to "Scientific Literacy". I set out to provide a good background in science in 100 paragraphs. I ended up with 104. Thoroughly learn everything in these paragraphs and you will have the strong background in science that everyone should have in the Twenty-First Century.
