Understanding Pressure Concepts

Front

Pressure

Back

Pressure is the force applied per unit area.

Front

How is pressure calculated mathematically?

Back

P = F / A

Front

What units are commonly used to measure pressure?

Back

Pascals (Pa), atmospheres (atm), bar, pounds per square inch (psi)

Front

What is atmospheric pressure and how does it change with altitude?

Back

Atmospheric pressure decreases with altitude.

Front

Explain the relationship between pressure and volume in gases.

Back

Pressure and volume are inversely related in gases; as volume decreases, pressure increases.

Front

What is Pascal's principle and how does it apply to pressure?

Back

Pascal's principle explains that pressure applied to a fluid in a closed system is transmitted equally in all directions.

Front

How does temperature affect the pressure of a gas?

Back

Temperature increases lead to an increase in gas pressure, assuming volume is constant.

Front

What is the difference between gauge pressure and absolute pressure?

Back

Gauge pressure is relative to atmospheric pressure; absolute pressure includes atmospheric pressure.

Front

Example of pressure in everyday life?

Back

The pressure exerted by a car tire on the road.

Front

What role does pressure play in fluid dynamics?

Back

Pressure is a key factor that influences fluid flow and behavior.
