MCQ

A tyre kept outside in sunlight bursts off after sometime because of

✓
Increase in pressure
B
Increases in volume
C
Both $(a)$ and $(b)$
D
None of these

✓

Answer

Correct option: A.

Increase in pressure

a
The volume of the gas present inside the typre is constant. As per Gay-Lussac's law, pressure of a given mass of gas varies' directly with the absolule temperature of the gas, when the volume is kept constant.

So, when kept in sunlight, the temperatuve rises and the pressure also rises. This increased pressure increases the momenturt of the gas molecules which exerts pressure on the walls of the typre and it bursts.

correct choice - option - $A$

The principle of ‘parallax’ is used in the determination of distances of very distant stars. The baseline $AB$ is the line joining the Earth’s two locations six months apart in its orbit around the Sun. That is, the baseline is about the diameter of the Earth’s orbit $\approx 3 \times 10^{11}\;m$. However, even the nearest stars are so distant that with such a long baseline, they show parallax only of the order of $1”$ (second) of arc or so. A parsec is a convenient unit of length on the astronomical scale. It is the distance of an object that will show a parallax of $1”$ (second of arc) from opposite ends of a baseline equal to the distance from the Earth to the Sun. How much is a parsec in terms of metres ?
