Which best describes the direction of heat?

from a substance with no thermal energy to a substance with high amounts of thermal energy

from a substance with less thermal energy to a substance with more thermal energy

from a cooler substance to a warmer substance

from a warmer substance to a cooler substance

Answer: Heat - --from a warmer substance to a cooler substance

Explanation: Heat can be transferred from a hotter substance to a cooler substance. This can be done through three methods;

Conduction, Convention, Radiation

Conduction - When substance is been heated movement of particles increases causing collision between hotter particles and cooler particles. This continue until the temperature is in equilibrium. Metal is a good conductor of heat.

Convention - It is often associated with liquid and gases. hotter area of liquid moves and meet with cooler liquid. The cooler liquid then takes place of the hotter liquid until equilibrium is attain. This occurs while boiling water

Radiation - It doesn't need a means of transmission. It is gotten from infared emission. Infared emission increases when temperature increases.
