A bicycle tyre is filled with air having pressure of $270 kPa$ at $27 ° C$ . The approximate pressure of the air in the tyre when the temperature increases to $36 ° C$ is

Options:

Answer:

Solution:

Given here, $P_{1} = 270 kPa, T_{1} = 27 + 273 = 300 K, T_{2} = 36 + 273 = 309 K$

Ideal gas equation is given by $P V = n R T$ .

Considering isochoric process, i.e., constant volume so $P \propto T$

Thus, $\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}$

$\Rightarrow P_{2} = \frac{P_{1}}{T_{1}} \times T_{2} = \frac{270 \times (309)}{300}$

$= 278 kPa$
