Alka was making tea in a kettle. Suddenly she felt intense heat from the puff of steam gushing out of the spout of the kettle. She wondered whether the temperature of the steam was higher than that of the water boiling in the kettle. Comment.

The boiling point of water is 100°C. With a continuous supply of heat, the temperature of boiling water does not rise as the extra heat supplied turns water into steam. Hence, steam has a lot of latent (hidden) heat which can cause severe burn. That’s why Alka felt intense heat from the puff of steam gushing out of the spout of the kettle.
