Heat

• Heat is when it is moving (in-transit)
• Moves from a body or substance with WARM temperature to a COOLER temperature until SAME TEMP.
• Heat cannot be contained in a substance
• The flow of heat will stop if the two bodies are balanced or the same when it is under THERMAL EQUILIBRIUM.
• Heat is a transfer of thermal energy between objects due to temperature differences.
• Two objects in contact are in thermal equilibrium when there is no flow of thermal energy.
• Large or shallow containers have more surface area, resulting in faster cooling. A smaller container has less surface area and a lower cooling rate. Container material also affects real-life heat losses.
• When you add heat to an object, the particles begin to move faster, resulting in greater kinetic energy. They also expand and take up more space.
• The fast-moving air from the fan relieves the warmer air that is in direct contact with our skin.
