Cards in this deck (13)
- 1How can you increase the pressure?You can increase the pressure by
-Increase the force
Or
-Reduce the surface area so there is a greater force acting on a smaller surface area resulting in a higher pressure. - 2How can you decrease the pressure?You can decrease the pressure by:
-Decreasing the force
-Increasing the surface area which would mean a smaller force can spread out on a bigger surface area resulting in a smaller pressure as it is less concentrated in one area. - 3What is the equation for pressure?Pressure:Force/Area
- 4More ______ liquids exert a greater pressureDenser
-fool-
-.- - 5Why is pressure exerted on balloon walls?In a balloon,the gas particles move more RANDOMLY and collide with WALLS each collision results in a force and as there are billions of collisions this leads to pressure being exerted on the balloons walls.
- 6A high pressure is when aa large force over a small surface area
- 7A low pressure is whena small force over a big surface area
- 8Liquid can be compressed to a certain point until the particles are close together so you cant compress themRandom fact you better memorise right now.
- 9High pressure is concentrated into a small areaMEMORISE BIOTCH
- 10LOW PRESSURE: evenly spread outmemoise
- 11Pressure in liquids gets denser as you go down becausemore weight of water
- 12Pressure in a fluid equationHEIGHT X PRESSURE X GRAVITY
or something idek - 13What is pressure?Force acting per unit area on a surface
