A sudden drop in the reading of the barometer indicates that the weather will be stormy. This drop signals a decreasing atmospheric pressure associated with stormy weather conditions, including precipitation, strong winds, and turbulent weather patterns.

We slip on muddy roads due to lack of friction. Muddy surfaces have reduced frictional force between our shoes and the ground, causing slipping. Option A (Gravitational force) and B (Relative velocity) aren’t directly responsible, while option D (Excess of ...
The pressure inside the soap bubble is less than atmospheric pressure. Surface tension of the soap film creates a pressure slightly higher than outside, but still less than atmospheric pressure. This pressure difference keeps the bubble stable. Therefore, the correct ...
Water boils at temperatures below 100°C at high altitudes because atmospheric pressure decreases. With reduced pressure, water’s boiling point lowers. Gravity’s effect and mountain winds don’t significantly impact boiling point. Therefore, the correct explanation is the decrease in atmospheric pressure.
If the mass of the Earth remains the same and the radius decreases by 1%, then the value of ‘g’ at the surface of the Earth will increase by will increase by 2%. This is because gravitational acceleration ‘g’ is ...
Sometimes in the mountains, people start bleeding from the nose and mouth because atmospheric pressure decreases with increase in altitude. This decrease in pressure can cause blood vessels in the nose and mouth to rupture due to the reduced external ...
The purpose of shock mats and alternate capping layers in railway tracks is to enhance stability, reduce vibrations, reduce pressure and mitigate track degradation. Shock mats, also known as under sleeper pads (USPs), are used to absorb impact forces, reduce ...
During strong storms, light thatched or tin roofs blow away because the high velocity air flowing over the roof creates pressure on the roof surface and the pressure below the roof remains normal. Additionally, the roofs are not tied tightly, ...
When two pieces of ice are pressed together, the pieces stick together, Due to increased pressure, the melting point of ice decreases. This occurs because pressure disrupts the equilibrium between solid and liquid phases, lowering the energy barrier for melting.
Body weight varies with location on Earth’s surface due to differences in gravitational acceleration. It is maximum at the poles due to being closer to the Earth’s center, and minimum at the equator due to the centrifugal force caused by ...
