Did you aware that heat may be exchanged between two bodies of varying temperatures? Heat energy can be transferred from one body to the other or from one location in a body to the other. And which of the following conditions must exist for heat to flow from one object to another
A temperature differential between two bodies is required to permit heat transmission. This indicates that the temperatures of both bodies must be different, with one being higher than the other in order for heat to move from one to the other.
This indicates that no heat transmission happens between two bodies that are both at the same temperature. At the same time, it is critical to understand that heat only moves from a hotter body to a colder one. Although it may seem intuitive, this rule is critical in thermodynamics.
Assume you’ve made a cup of tea for yourself. Because the tea is quite hot, say at 80°C, you leave it in a room with a temperature of 25° C for a while to cool down. This is the first heat transfer law. Heat transmission between two bodies occurs only when their temperatures are significantly different.
After some time, you return to discover that the tea in the cup has cooled to, say, 50°C, and you take a taste of it. This is the second heat transfer law. Heat will only move from a higher temperature body to a lower temperature body. It is not conceivable to create a situation in which heat goes from the room at 25° C to the cup of tea at 80° C, further heating it.
Heat may be transferred in three ways: conduction, convection, and radiation. Heat transfer happens anytime there is a temperature difference between states of matter, and heat transfer occurs exclusively in the direction of decreasing temperature, that is, from a hot object to a cold item.
Heat, represented by the symbol Q and the unit Joule, is selected to be positive when heat enters the system and negative when heat exits the system . Heat flow is caused by a temperature differential between two bodies, and it is zero if TS = TE.
Conductors are materials that enable electricity to travel through them. Copper wire is an excellent conductor. Insulators are materials that do not allow electricity to travel through them. Plastic is an excellent insulator.
