Problem $3$: Your friend claims to have

invented an apparatus that uses

saturated steam at $100C$ to heat a

reactor to $200C.$ Here are the details:

For every $1kg$ of saturated steam used,

it makes $2000kJ$ of energy available at

$200C.$ The apparatus has an unlimited supply of cooling water available at $0\backslash$deg C$.$

Is this process possible?
