Heat and Temperature
Heat and Temperature
Heat is the transfer of energy from a hot body.
The sense of touch can be used to understand the degree of hotness or coldness of something. But the sense of touch is not reliable and cannot be always used to say how much hot anything is. Moreover, using the sense of touch can be risky in case of something very hot. Thus, hotness of anything is measured in terms of Temperature in reliable way. To measure temperature a device called Thermometer is used.
Conversion from one scale to another:
K= C + 273
