Explain why the moisture gathers on the outside of a glass tumbler containing cold water?

2

Q. Explain why the moisture gathers on the outside of a glass tumbler containing cold water?

Ans. Because the water vapours present in the air get cooled and appear as droplets of water on coming in contact with the cold surface of the glass tumbler.


Q. Explain why in winter evenings and mornings, fog or mist collects in valleys?

Ans. This is because in winter evenings and mornings the temperature of the atmosphere is sufficiently low so as to cause the condensation of water vapours present in the atmosphere. The condensed water vapours being heavy, appear as fog or mist and tend to collect in valleys.

Q. Why is a small space left at the joint between the two rails ?

0

Q. Why is a small space left at the joint between the two rails?

A. Metals expand on heating and contract on cooling. A small space is left between each set of two rails of the railway line to allow for their expansion in summer and contraction in winter, respectively.

Q. Why can’t a petrol fire be extinguished by pouring water over it?
A. Water, being heavier, slips down and petrol will rise to the surface and continue to burn as before. Hence, water cannot be used for extinguishing petrol fire.

Q. Explain why one leans forward while climbing a hill.

0
Q. Explain why one leans forward while climbing a hill.
A. The person leans forward in order to keep himself in stable equilibrium. By leaning forward, he increases the base of the support, so that the vertical line passing through his centre of gravity may fall within the base. For similar reasons, a man has to bend backward while climbing down a hill.
Q. Why is it dangerous to allow extra passengers on the upper deck of a double-decker bus?
Or
Explain why passengers in a boat are not allowed to stand.
A. This is done so that the centre of gravity of the bus is not raised and the bus may not topple over due to unstable equilibrium. For the similar reason, passengers in a boat are not permitted to stand.

Q. Why is it more difficult to breathe on mountains than on plains ?

2

Q. Why is it more difficult to breathe on mountains than on plains?

A. With higher altitudes, the pressure of air goes on decreasing. The oxygen content in the air is also reduced considerably. We experience difficulty in breathing on mountains because the pressure of air outside is less as compared to the pressure of air inside the lungs.

Q. Why does ink leak out of a partially filled pen when taken to a higher altitude ?

A. The density as well as pressure of air goes on decreasing with altitude. When a partially filled pen is taken to a higher altitude, it leaks, because the pressure of air acting on the ink inside the pen is greater than the pressure of air outside.
