## Homework Statement

Find the mass of liquid lead at fussion temperature needed to heat up 1kg of liquid water from 20ºC to 60ºC, considering P = 1 atm, and a

**loss of 100 mg of water due to local vaporization**.

My question is: what do I do with that loss of mass? Do I calculate Q for m = (1000 - 0,1) g?

I'm really at loss with that.

Thanks.
