Question

Select the correct observation for an $8.21$ lit container, filled with $2$ moles of $He$ at $300$ K:

• A. It has pressure $6$ atm
• B. If it is an open rigid container,its pressure increases to $8atm$ on heating to $400$ K
• C. If it is closed non-rigid(like thin skin balloon),its volume increases to $16.42$ lit.on heating to $600$ K
• D. When connected with another similar empty container maintained at $150$ K while maintaining original container at $300K$, pressure reduces to $\frac{2}{3}$ atm.
