Question

The volume thermal expansion coefficient of an ideal gas at constant pressure is –

• A. T
• B. T²
• C. $\frac{1}{T}$
• D. $\frac{1}{T^{2}}$

Answer 1

Answer: (C)

$\frac{1}{T}$

Answer 2

At 'P' ® const. V µ T

$\frac{\Delta V}{\Delta T}$ = const., g = $\frac{\Delta V}{V}$×$\frac{1}{\Delta T}$ Ž g = $\frac{K}{V}$ = $\frac{1}{T}$
