SUMMARY

The discussion centers on applying Boyle's Law to a bicycle pump and tire system. Initially, the total volume of air is 1000 cm³, combining the 200 cm³ from the pump and the 800 cm³ from the tire. After the pump is used, the volume of air in the system changes, impacting the pressure within the tire. Using Boyle's Law, which states that pressure and volume are inversely related for a given mass of confined gas, the pressure in the tire can be calculated after the pump is pushed.

PREREQUISITES
  • Understanding of Boyle's Law and its mathematical formulation
  • Basic knowledge of gas laws in physics
  • Familiarity with pressure and volume units (atmospheres and cm³)
  • Ability to perform calculations involving inverse relationships
NEXT STEPS
  • Study the mathematical derivation of Boyle's Law
  • Explore real-world applications of gas laws in various systems
  • Learn about the ideal gas law and its differences from Boyle's Law
  • Investigate the effects of temperature on gas pressure and volume
USEFUL FOR

Students studying physics, engineers working with pneumatic systems, and anyone interested in the practical applications of gas laws in everyday scenarios.

A bicycle pump contains 200 cm³ o fair and is connected to a bicycle tyre.
The volume of the tyre is 800 cm³. The pressure of the air in the tyre (it is `flat´) is 1.0 atmosphere, the same as the air initially?
A) What is the total volume of the air initially? (=volume1)
B) What is the volume of air after the pump is pushed in? (=volume2)
C) What will be the pressure in the tyre then?


Can you please give me the answers?
If possible explain it?
Would be nice of you.
Thankyou!

Diana,

Sorry, but PF rules discourage "giving answers". Plus, where is the fun in that? We do, however, answer questions related to your problem solving process. Go ahead and attempt a solution--if you are confused about something, say so.
