Question
A container has N molecules at absolute temperature T. if the number of molecules is doubled but kinetic energy in the box remain the same as before the absolute temperature of the gas is
Open in App
Solution
The
absolute temperature is the temperature at which the molecules of a system
possess the lowest possible energy. You can also say that at this temperature
the molecules of a substance have the Minimum possible energy.
As
the molecules of a substance approach this temperature, their movement drop
towards zero.
So
if you double the number of molecules in a container at its absolute
temperature, it will make no difference to their Kinetic Energy. The reason is
that molecules have kinetic energy due to the motion. But when they have zero
movement, they will have no kinetic energy.
The
absolute temperature of a gas is taken as ABSOLUTE ZERO.
The
absolute zero in Kelvin Scale is 0K.
The
absolute zero in Celsius scale is -273.15 C
