Question

Why can't we use the formula Heat absorbed / given = mc∆t over here..​

Answer 1

Answer:

The formula mct can be used if it is converted water at 100 degree. Here additional heat ml is required since water at 30 degree cel is converted to steam at 100deg cel

Answer 2

We can't just use the formula Heat absorbed / given = mc∆T as there is no term of latent heat involved

Explanation:

• Here the formula of Q = mc∆T has been used but there is an extra term mL too.

• Here L is the latent heat of vapourization

• We know that water gets converted into steam at 100°C

• When we heat water to convert it into steam, the water isn't converted into steam just when it reaches 100°C, rather it requires extra heat, only then it is converted into the steam

• This "extra heat" is calculated by mL, where m is mass and L is latent heat of vapourization.

• In Hindi latent heat is known as "गुप्त ऊष्मा" which perhaps makes the term more clear as it is the energy that remains hidden

Hope this answer is helpful.
