Question

Heat is supplied to convert 1.26 kg of water at 100°C to steam at 100°C? Latent heat of vaporization of water is

2.26 x 106 J/kg.
a
What is latent heat, and how does it affect the temperature of a substance?
​

Answer 1

latent heat = 2.84 x 10^6

and the temperature increase

Step-by-step explanation:

Answer 2

Given that,

Mass of water = 1.26 kg

Latent heat of vaporization of water
`L=2.26*10^(6)\ J/kg`

We need to calculate the latent heat

Using formula of latent heat

`Q=mL`

Where, Q = energy

m = mass

L = latent heat of vaporization

Put the value into the formula

`Q=1.26*2.26*10^(6)`

`Q=2847600\ J`

`Q=2.84*10^(6)\ J`

The temperature changes liquid to steam.

So, The temperature will be increases.

Hence, The latent heat is
`2.84*10^(6)\ J` and temperature increases.
