Question

How much heat will be required to convert 20g of water at 100⁰C into steam at 100⁰C ? (Specific latent heat of vaporization of water = 540 cal/g)

Answer 1

Explanation: Heat required will be 10800 cal

Given Data:

Mass, m = 20g

Temperature, T = 100⁰ C

Specific latent heat of vaporization of water = 
`540\,cal/g`

Heat is given by,

H = m×
`L_(v)`

H = 20g ×
`540\,cal/g`

H = 10800 cal
