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 .
