That's correct! And if we touched the flame with something, that would be convection.
Does anyone know what the 2nd Law of Thermodynamics is?
And heat is held in insulators, such as wood and paper.
Yes! Heat always transfers from hot to cold until it reaches equilibrium.
It transfers through conductors, such as metal.
Is it when heat transfers from hot to cold?
An example of the 2nd Law would be when you put ice cubes in your water. Then if you leave it for a couple hours, the ice cubes have melted. The water, however, is cold. This is just the ice cubes and water changing to reach equilibrium.
Then there is the 3rd Law. This law is about absolute zero. Absolute zero would be when a heat and movement inside something is zero. This becomes very complex to try and copy, but believe it or not, the coldest place that is closest to absolute zero is labs that are here on Earth.
Even though labs have gotten close to absolute zero, absolute zero is impossible to reach, this is because absolute zero happens when there is no particle movement, but particles in an object are always moving.
