Question
Is it true that it takes more energy to vaporize $1 \mathrm{~kg}$ of saturated liquid water at $100^{\circ} \mathrm{C}$ than it would at $120^{\circ} \mathrm{C} ?$
Step 1
At 100°C, the water is at its boiling point under normal atmospheric pressure (1 atm). When water reaches its boiling point, it starts to vaporize, turning from liquid to steam. Show more…

Is it true that it takes more energy to vaporize $1 \mathrm{kg}$ of saturated liquid water at $100^{\circ} \mathrm{C}$ than it would at $120^{\circ} \mathrm{C} ?$
Does the amount of heat absorbed as 1 kg of saturated liquid water boils at $100^{\circ} \mathrm{C}$ have to be equal to the amount of heat released as $1 \mathrm{kg}$ of saturated water vapor condenses at $100^{\circ} \mathrm{C} ?$
