Achamber with a fixed volume of 1.0 meters cubed contains a monatomic gas at 3.00 *10^k. the chamber is heated to a temperature of 400 k. this operation requires 10.0 j of heat. how many gas molecules are in the chamber

Explanation:

Given

Volume of fixed chamber

Initial Temperature

Final Temperature

Heat Supplied

From First law of thermodynamics

Change in internal energy of the system is equal to heat added minus work done by the system

as the volume is fixed therefore work

thus

for mono-atomic gas is

and 1 mole contains

thus  No of molecules

No of molecules

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
