Question

How much heat transfer is required to completely boil 3500 g of water (already at its boiling point of 100°C) into a gas?answer in joules

Answer 1

7910000 J

Step-by-step explanation:

The heat transfer to phase change is calculated as:

`Q=mH_v`

Where m is the mass and Hv is the heat of vaporization.

For water, Hv = 2260 J/g.

So, replacing m = 3500 g and Hv = 2260 J/g, we get:

Q = 3500 g (2260 J/g)

Q = 7910000 J

Therefore, the answer is:

7910000 J
