Question

What is heat??????????​

Answer 1

Answer:

Heat is the form of energy that is transferred between systems or objects with different temperatures (flowing from the high-temperature system to the low-temperature system). Also referred to as heat energy or thermal energy. Heat is typically measured in Btu, calories or joules.

Answer 2

$\huge \bold \purple{answer}$

heat is a form of energy.

By definition, heat is thermal energy transferred from one thing to another. And like other forms of energy, heat can be used to perform work. It can warm things up, cool things down, generate electricity, and be transmitted for use in different locations.

heat is very important in our daily life in warming the house, cooking, heating the water and drying the washed clothes. The heat has many usages in the industry as making and processing the food and manufacture of the glass, the paper, the textile,etc;

It is below us, in the earth as geothermal energy. It's above us, radiating from the sun as solar thermal energy. And it's a byproduct of so many of our small and large industrial processes. The combustion of a car's engine produces heat, as does the large generator that powers the grid. So does the factory producing cement, or glass, or steel.  

Unfortunately, most of the heat that is produced in the world as a byproduct of a process is simply vented into the atmosphere. This is where we get the term "waste heat", and there's a lot of it.

1. Warm something up

Heat can be collected and put to beneficial use where a heat demand is nearby. A common form of heat utilization is Combined Heat and Power (CHP) whereby heat from a power generation facility is captured and used for something like heating a building, pool, or greenhouse.

2. Cool something down

It sounds counterintuitive, but heat can actually generate refrigeration or cooling. For example, a hospital that combusts used equipment could use the hot exhausts to create cooling for refrigeration used in the same facility.

3. Generate electricity

Heat can be converted into electricity in a variety of ways. In each, the conversion process requires no additional fuel and produces no additional emissions. In that way, it is similar to solar or wind, but it has the potential benefit of operating 24 hours per day rain or shine... as long as the heat source is operating.
