How do you increase the pressure by keeping (a) area unchanged and (b) force unchanged? In given diagram
Answers
PRESSURE=FORCE /AREA
IN a YOU DONT WANT TO CHABGE THE AREA
then you have to increase the force
in b YOU DONT HAVE TO CHANGE THE FORCE
THEN YOU HAVE TO CHANGE THE AREA
Answer:
Starting Diagram Shows you That More Force is Acting on Left
Less Force Acting on Right that
Explanation:
You can increase the pressure by changing either force or area or both. a) If you want to increase pressure while keeping area unchanged, you have to change force. Since pressure is directly proportional to force, increase the force.
Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law (especially in France), is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases. A modern statement of Boyle's law is:
The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.[1][2]
Mathematically, Boyle's law can be stated as:
{\displaystyle P\propto {\frac {1}{V}}}P\propto {\frac {1}{V}} Pressure is inversely proportional to the volume
or
{\displaystyle PV=k}PV=k Pressure multiplied by volume equals some constant {\displaystyle k}k
where P is the pressure of the gas, V is the volume of the gas, and k is a constant.
The equation states that the product of pressure and volume is a constant for a given mass of confined gas and this holds as long as the temperature is constant. For comparing the same substance under two different sets of conditions, the law can be usefully expressed as:
{\displaystyle P_{1}V_{1}=P_{2}V_{2}.}P_{1}V_{1}=P_{2}V_{2}..
This equation shows that, as volume increases, the pressure of the gas decreases in proportion. Similarly, as volume decreases, the pressure of the gas increases. The law was named after chemist and physicist Robert Boyle, who published the original law in 1662.
