Question
- how does carnot cycle operates
- why does absolute zero not correspond to zero energy
Solution
- The Carnot cycle consists of the following four processes: A reversible isothermal gas expansion process. In this process, the ideal gas in the system absorbs qin amount heat from a heat source at a high temperature Th, expands and does work on surroundings.

As you know , absolute zero means the temperature in Kelvin scale is 0K or in Celcius scale is -273.15°C . actually, in this temperature, Gaseous molecule be rest , there is no motion of molecule in their position. due to this reason we say that energy of Gaseous molecule at this is zero. means absolute zero correspond to zero energy .
well, it's hard to achieve Absolute zero or 0K or -273.15°C temperature. it is just theoretical. molecular can't achieve Absolute zero.
