Answer:
Steel is almost 2.9 times heavier the aluminium.
Answer:
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
