Question

At what temperature in the Fahrenheit scale does water boil? Explain what happens when we supply heat energy to water until it changes its state. What is this heat energy called?

Answer 1

Boiling temperature of water $($ in $℃)=100℃$

$\therefore$ Boiling temperature of water $($in $℉)=\frac{9}{5}\times 100+32$

$=212℉$

when we supply heat energy to water, the internal energy of water increases till it changes its state. The heat energy required to change it state from liquid to vapor is called as the Latent heat of vaporization.
