Telangana Board Solutions for Chapter: Heat, Exercise 1: Exercise 1

What do you observe in the surroundings in terms of cooling or heating when water vapour is getting condensed?

Convert the following into Kelvin scale (i) $20℃$ (ii) $21℃$ (iii) $-273℃$.

How do you appreciate the role of the higher specific heat of water in stabilizing atmospheric temperature during winter and summer seasons?

How much energy is transferred when $1 \mathrm{g}$ of boiling water at $100℃$ condenses to water at $100℃$?

How much energy is transferred when $1 \mathrm{g}$ of boiling water $100℃$ cools to water at $0℃$?

How much energy is released or absorbed when $1 \mathrm{g}$ of water at $0℃$ freezes to ice at $0℃$?

How much energy released or absorbed when $1 \mathrm{g}$ of steam at $100℃$ cools to ice at $0℃$?

Suppose that $1\mathrm{L}$ of water is heated for a certain time to rise its temperature for $2℃$. If $2\mathrm{L}$ of water is heated for the same time, how much of its temperature would rise?
