Pressure of a Gas
Heating a gas in a sealed can raises pressure because particles hit harder and more often. Reducing volume at fixed temperature also raises pressure (more hits per second on a smaller wall).

Pressure of a Gas
What is it?
Heating a gas in a sealed can raises pressure because particles hit harder and more often. Reducing volume at fixed temperature also raises pressure (more hits per second on a smaller wall).
In simple words
- Heating a gas in a sealed can raises pressure because particles hit harder and more often.
- heat raises pressure
- smaller volume
- collisions
Important terms
Pressure Of A Gas: Heating a gas in a sealed can raises pressure because particles hit harder and more often. Reducing volume at fixed temperature also raises pressure (more hits per second on a smaller wall).
What you should learn
- Define and explain pressure of a gas.
- Apply pressure of a gas to a focused FBISE question.
- Check the answer for correct terms, evidence, working, and units.
Examples
- heat raises pressure
- smaller volume
- collisions
CORE UNDERSTANDING
Heating a gas in a sealed can raises pressure because particles hit harder and more often. Reducing volume at fixed temperature also raises pressure (more hits per second on a smaller wall).
EXAM APPLICATION
State the correct term, connect it to the chapter rule or evidence, and use a clear example or calculation.
Recommended for Class 10
Full school-level explanation
Heating a gas in a sealed can raises pressure because particles hit harder and more often. Reducing volume at fixed temperature also raises pressure (more hits per second on a smaller wall).
Learn the idea, then use it:
