What is pressure? how we can reduce pressure? explain it by taking one practical application |
|
Answer» Pressure is the amount of force exerted by a substance.We can REDUCE pressure by changing the following of a substance-1.reducing volume2.reducing mass3.reducing densityThe practical explanation is given below.Explanation:Materials-1.Small piece of Paper of size 2sq.cm 2.Heavy metal ball 3.Pressure measuring instrumentProcedure-1.Measure the pressure of the paper then measure the pressure of the heavy metal ball.Note down both the measurements.Observation-The pressure exerted by the ball is more. This is because pressure DEPENDS on the mass,volume and DENSITY of a substance.In EVERY ASPECT,the ball is greater.So,pressure exerted by the ball is greater.Conclusion-This proves that pressure of a substance depends on its mass,volume and density.Hope you got your answer!!!!!!! |
