You need to size a continuous vaporizer for a child$$s sick room. The device

received liquid water at $25$C and $1$ atm and produces steam at a rate of $0\mathrm{.}7$ g$/$min$.$ At what

rate must energy be supplied if the device is $100\%$ efficient? The standard heat of

vaporization of water is $2256\mathrm{.}9$ kJ$/$kg and the specific heat capacity of water is $1$ cal$/$g$-$C
