Physics - Gas Pressure 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: LunaShomeiRoseCreated on: 23-10-18 20:08 What causes pressure in a gas? Particles colliding with walls of container they're kept in 1 of 7 The particles reflect at __ degree angle 90 degree (right angle) 2 of 7 Increasing volume of container would ___ pressure. Why? decrease. Particles are further apart so travel further before colliding, reducing pressure 3 of 7 Gas pressure is i___ p___ to volume (volume increases, pressure decreases) Inversely proportional 4 of 7 We can show this with this equation: pV = contant. What does pV mean? p = pressure. V= volume 5 of 7 Gas has a 3m(cubed) volume and 400,000 Pa (pressure). Volumes increased to 6m(cubed). Calculate presuure Volume increased by 3. So presuure has decreased by 3. 400,00/3 = 133,333 Pa 6 of 7 Gas has 5m(cubed) volume and pressure 150,000 Pa. Pressure decreased to 50,000. Work out volume Pressure decreased by 3. Volume increases by e. 5 x 3 = 15m(cubed) 7 of 7
