Question

4. How are temperature and hotness of a body related?
5. What do you mean by ‘upper fixed point'?
6. Why does a clinical thermometer have a kink in its stem?
please give me the right anwer​

Answer 1

Answer:

4. Heat refers to energy and how much energy is transferred to the body determines its temperature. So the relationship is pretty simple between the two. Hotness of a body is the energy quotient in a body which when transferred induces the rise or fall in temperature of a body.

5. The upper fixed point, or steam point, is the temperature of pure boiling water at normal atmospheric pressure. Note that the fixed points are defined using common physical phenomena so that they can be easily reproduced.

6.In a clinical thermometer kink plays an important role. kink prevents the mercury present in the capillary to fall back in the bulb. So it separates the mercury at high temperature and cool mercury and allows the user to note the reading when the thermometer is taken out.
