Heat is a form of energy which flows from a hotter body to a colder one because of the difference in temperature. The study of heat in physics is called thermodynamics.
As a type of energy it is measured in joules (J). How hot or cold something is, is measured with various temperature scales: Celsius, Fahrenheit or Kelvin are among the most frequently used ones.
This infograph takes you on a visual tour of what’s hot or not in the universe, or from absolute hot to absolute cold. Planck temperature or absolute hot is related to the big bang. It’s hard to imagine anything hotter than that. Theoretically it is the highest possible temperature at which even black holes evaporate.
Show this fun infograph to your students and get down to studying the presented information abundant in fun details about heat and temperatures.
