Answer:
The temperature of both boiling water and steam is 100°C,
but steam gives out more heat (due to latent heat of vaporization) in
comparison to boiling water.
It is because, when water changes into steam, it absorbs
latent heat of vaporization, but when steam condenses to form water, an equal
amount of latent heat is given out without changing the temperature.
Hence, she felt intense heat from puff of steam gushing
out of the spout of the kettle.
