WebAccording to thermodynamic systems, heat transfer is defined as The movement of heat across the border of the system due to a difference in temperature between the system and its surroundings. Interestingly, the difference in temperature is said to be a potential that causes the transfer of heat from one point to another. It happens in liquids and gases. The total heat gained by the system can be calculated by using the formula for heat transfer as mentioned above, In addition, many applied branches of engineering use other, traditional units, such as the British thermal unit (BTU) and the calorie.The standard unit for the rate of heating is the watt (W), defined as one joule per second..
