How many Joules of energy are required to boil 350g of water at 100 degrees Celsius?

Explanation:

Hello!

In this case, since this is the vaporization process of water, we need to keep in mind that the enthalpy of vaporization of this compound is 2.256 kJ/g, for 350 g, we obtain:

Because the process is carried out at 100 °C, the boiling temperature of water, already.

Best regards!

the product of the pressure and volume is also constant
