Question

The amount of heat energy required by 500g of water to convert it into vapour at its boiling point in joules is​

Answer 1

Answer:It depends on what temperature the water is starting at.

Explanation:

If the water is in solid form it would go through 2 phase changes. That equation is:

q = m Δ H f

The  Δ H f

should be given to you or easily accessible.

However, when calculating the amount of heat necessary to heat to a certain temperature you need the initial temperature. That equation looks like this:

q = m C s Δ T
