Question $1.$ A membrane divides a rigid, well$-$insulated tank inti two parts. The left side contains $1$mol

of an ideal gas at $10$ bar and $300K,$ Right hand side contains nothing $--$ It is a vacuum. At some point, the

membrane ruptures with a bang, and the gas fills the entire tank.

a$)$ Is this a reversible or irreversible process?

b$)$ Apply the $1^{st}$ Law of Thermodynamics to the whole tank.

c$)$ What is the final temperature if this ideal gas after the mem brane ruptures.
