**Introductory Exercise 17.1**

**Ques 1: What is the value of(a) 0°F in celsius scale?(b) 0 K on Fahrenheit scale?Sol:**

Putting T

Sol:

Putting T

Sol:

∴ T

Now using the equation,

Putting T

Sol:

Putting T

We get, T

Sol:

Putting T

T

α

Sol:

Temperature is decreased. Hence l or T will decrease. So it will gain time.

= 15.55 s

Sol:

ρ

Or percentage of volume above water level will first increased then decreased.

Sol:

Neglecting γ

Sol:

Since, αB >α

On cooling brass will contract more.

Sol:

At constant pressure we can write the above equation as

PdV = nRdT .

∴ ...(ii)

Substituting in Eq. (ii),

or ...(iii)

Now we have an equation,

From Eqs. (iii) and (iv), we get, γ= 1/T
