Question $1(1$ point$)$

You drop a $1$ kg chunk of ice $($at $0C)$ into an insulated tank containing $1$ kg of steam $($at $100C).$ Assuming no contents leave the tank, what is the final temperature when equilibrium is reached? ${10}^5\frac{J}{k}g)$

Between $0C$ and $50C$

$100C$

Between $50C$ and $100C$

Greater than $100C$

$50C$
