Term
 Because the formule for pressure is p=f/a, calculate the pressure exerted by 10n on an area of 1m3
Definition
 p=f/ap=10/1p=10 pa
Term
 How does the air inside a container exert pressure on the wall of the container
Definition
 Pressure is caused by the force exerted by lots of collisions between the fast moving air particles and the container walls
Term
 why does a solid expand when heated?
Definition
 Heat causes the particles of the solid to have higher kinetic energy which causes the particles to vibrate with each other more vigorously, making the gaps between particles larger and expanding the solid
Term
 Because the formule for heat capacity is Q=mc^T, find how much energy it takes to heat a copper kettle by 1* when the kettle has a mass of 3kg and a heat capacity of 380jkg
Definition
 Q=mc^T =3.5 x 380 x 1 =1330j
Term
 What is Brownian motion?
Definition
 Brownian motion is the random movement of microscopic particles suspended in a liquid or gas, caused by collisions with molecules of the surrounding medium
