Hey there,

1 is hotter
2 is colder

So heat is a form of energy right?
And energy flows from an area of high concentration to an area of low concentration.
So the hotter one area, the more energy it has right?
And colder areas have lesser amounts of energy because they don’t have heat(energy)

So heat must travel from hot places to cold places.

Its not just heat but most forms of energy,eg electricity.

So the answer is hotter and colder.

Hope this helps

The heat always flows from a hotter place to a cooler place.

Spontaneous heat transfer occurs from a high temperature to a low temperature, as explained by the second law of thermodynamics.

Further explanation

The Kelvin-Planck formulation or the second law of thermodynamics states that it is not possible to make a heat engine that works in a cycle that merely converts the heat energy obtained from a reservoir at a certain temperature entirely into mechanical effort. The second law of thermodynamics says that heat flow has a direction; in other words, not all processes in the universe are reversible. For example, if a polar bear sleeps in the snow, the snow under its body will melt because of the heat from the bear's body. However, the bear cannot take the heat from the snow to warm the body. Thus, the heat energy flow has a direction, from hot to cold. One important application of the second law is the study of heat engines.

The basic forms of mass transfer are:

Conduction or diffusion

Energy transfer between objects that are in physical contact with a source of heat.

Convection

The transfer of energy between an object and its environment is due to the movement of fluids originating from heat sources.

Advection

Energy transfer from one location to another as a side effect of energy moving objects.

Radiation

Energy transfer from or to an object due to the release or absorption of electromagnetic radiation and does not have to make physical contact with sources of heat.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
