Question

while deciding the unit for heat which temperature interval is chosen why ​

Answer 1

Answer:

As a form of energy, heat has the unit joule (J) in the International System of Units (SI). However, in many applied fields in engineering the British thermal unit (BTU) and the calorie are often used. The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second.

Answer 2

Explanation:

While defining the unit for heat, the temperature range between 14°C to 15.5°C is chosen.

If we take different

temperature range than 14°C

to 15.5°C, the amount of heat required will be slightly different. It is,

therefore, essential to define a specific temperature range while.

defining the unit of heat.
