Question

isothermal process


class 12 th physics​

Answer 1

Answer:

Isothermal refers to a process in which a system changes—whether it be the pressure, volume and/or contents—without the temperature changing. From the point of view of the first law of thermodynamics, this means that the internal energy of the system is unchanged, since temperature is a measure of the average kinetic energy of molecules within the system.[1] This then looks like:

and consequently,

where:

is the change in internal energy

is heat

is work

Answer 2

Answer:

A refrigerator works isothermally. A set of changes take place in the mechanism of a refrigerator but the temperature inside remains constant. Here, the heat energy is removed and transmitted to the surrounding environment. Another example of an isothermal process is the heat pump.
