Suggest some daily life phenomena associated with atmospheric pressure you observe around you.

Drinking with a Straw: When you suck on a straw, you create a vacuum in it. This reduces the pressure inside the straw. The atmospheric pressure outside the straw then pushes the drink up into your mouth.

Weather Changes: Changes in atmospheric pressure can often signal changes in the weather. High pressure usually means good weather, while low pressure often brings clouds and rain.

Boiling Water: The boiling point of water decreases as atmospheric pressure decreases. That's why it takes longer to cook food at high altitudes, where the atmospheric pressure is lower.

Breathing: When we inhale, the diaphragm moves down and creates a low pressure area in our lungs. The atmospheric pressure then pushes air into our lungs. When we exhale, the process is reversed.

The Functioning of Syringe: The syringe works on the principle of atmospheric pressure. When the piston of the syringe is pulled, the volume inside the syringe increases, causing the pressure inside the syringe to decrease. The atmospheric pressure then pushes the liquid into the syringe.

The Pop Sound of Opening a Soda Can: When you open a soda can, you hear a pop sound. This is because the pressure inside the can is higher than the atmospheric pressure outside. When you open the can, the pressure inside drops quickly to match the atmospheric pressure, creating the pop sound.

Barometers: Barometers are devices used to measure atmospheric pressure. They work by balancing the weight of mercury in a glass tube against the atmospheric pressure, much like a scale.

The Functioning of Aneroid Capsules: Aneroid capsules are used in aneroid barometers and altimeters to measure pressure. They are sealed capsules with a partial vacuum inside. When the atmospheric pressure changes, the capsule either expands or contracts.

The Functioning of Air Pumps: Air pumps work by creating a low pressure area inside a chamber. The atmospheric pressure then pushes air into the chamber.

The Functioning of Vacuum Cleaners: Vacuum cleaners work by creating a low pressure area inside them. The atmospheric pressure then pushes air (and dust and dirt) into the vacuum cleaner.
