explain now pressure plays a role in our day to day activities in 200 words
Answers
Answer:
- The area of the edge of a knife’s blade is extremely small. This creates a pressure high enough for the blade to cut through a material.
- Syringes are used to take blood for blood tests. The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn.
- When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.
- Skis have a large area to reduce the pressure on the snow. This ensures that the skis do not sink into the snow too far.
- The pressure under the studs on the soles of football shoes is high enough for them to sink into the ground, which gives extra grip.
- A vacuum cleaner has a fan inside that creates a low pressure inside the device. Consequently, air and dirt particles are sucked into the device.

Applications of Pressure in Daily Life
The area of the edge of a knife's blade is extremely small. ...
Syringes are used to take blood for blood tests. ...
When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.
As the pressure decreases, the amount of oxygen available to breathe also decreases. At very high altitudes, atmospheric pressure and available oxygen get so low that people can become sick and even die.
Increase activity and exercise more. ...
Lose weight if you're overweight. ...
Cut back on sugar and refined carbohydrates. ...
Eat more potassium and less sodium. ...
Eat less processed food. ...
Stop smoking. ...
Reduce excess stress. ...
Try meditation or yoga.
Air pressure (atmospheric) helps us to drink from bottles or cans. As liquid comes out, air goes in to fill the vacuum created. So fluid comes out. If there is no change in pressure of air, it does not happen.
When we rise to the moment with integrity and gusto, we always improve (even when we don't win), and we let people know they can count on us to charge into the arena and fight the good fight, no matter what. Pressure helps us grow, helps keep us honest, and helps us engage with life.
To increase pressure - increase the force or reduce the area the force acts on. To cut up your dinner you can either press harder on your knife or use a sharper one (sharper knives have less surface area on the cutting edge of the blade). To reduce pressure - decrease the force or increase the area the force acts on.it saves time . it makes us focus . preservers our interest . this are the three advantages of pressureThe pressure exerts a force on the surface of the liquid and causes it to move a specific distance that is proportional to the magnitude of the force.
