Heat goes from where it's hot to where it's not. It's thermodynamic pressure or a difference in temperatureor a temperature gradient that causes heat to move.
They travel in waves.
Rradiation is the only way that heat can travel in a vacuum.
Sound doesn't travel in heat. It travels in a physical medium.
Some, but not all. Some materials are insulators- heat does not travel well through them.
No, heat does not require a medium to travel. Heat can be transferred through conduction, convection, or radiation, and can travel through a vacuum as well.

exothermic heat by radiation in physics
Lets look at a vacuum and heat. Heat is the treansfer of energy from one piece of matter to another. A vacuum is the absence of matter. Heat cannot transfer in a vacuum because there must be matter in close proximity to other matter for heat to travel.
Heat travels from Hot to cold. Not up!
Heat will always travel from an area of higher temperature to an area of lower temperature, following the principle of thermal equilibrium.
Yes, heat can transfer by the mode of radiation.
Heat travels through waves of insulation through metals and other materials. The only metals that heat does not travel through are aluminum and nickel.
