BOYLE'S LAW

  • OBJECTIVES

    • Describe in qualitative terms the effects of changes in pressure and volume on contained gases.

    • Calculate pressure or volume from the pressure - volume relationship of a contained gas at constant temperature.

    • PROBLEM

      • Variation between the pressure and volume.

      • HYPOTHESIS

        • The pressure and volume vary inversely proportional.

        • MATERIALS

          • A syringe

          • A graphic calculator

          • CBL

          • A pressure sensor.

          • PROCEDURE

          • Turn on CBL and the graphic calculator.

          • To program Chembio.

          • To put prove, channel, calibration, used stored in that order.

          • To press Triger in CBL after each measure bye the pressure sensor.

          • When you finish all measures to put in the graphic calculator “No repeat”, first curve, and Power L1, L2.

          • DATA

            • The equation for calculate the heat released is:

            • P1V1 = P2V2

            • P = pressure

            • V = volume

            • OBSERVATIONS

            • Table Nº1

            • ANALYSIS

            • CONCLUSIONS

              • When the pressure goes up, the volume goes down.

              • The relationship between pressure and volume is inversely proportional.

              • The product of volume and pressure at any two sets of conditions is always constant at a given temperature.

              • Pressure increased when volume decreased because the gas molecules have minor space and the container received most fight by the molecules inside its.

              • The collision of the particles in a gas with the walls of the container is gas pressure.

              • The pressure in the container increases in proportion to the number of gas particles inside its.

              • The gases' constituent corpuscles stand still always they are in contact whit others.

              • The gases' constituent corpuscles can compress them, this one explains their capacity for to decreased the volume when a exterior pressure affects them.

              • The volume of a container easily accommodates whichever number of particles.

              • The mechanics process in a laboratory make, sometimes, we obtain wrong answers.
