Term
 The formula's for Pressure and use of Barometer
Definition
 - The formula for pressure: P = F/A - The formula for Pressure under water: P =  ρ x g x h ( Pressure = Density x Gravitational field strength x Height ) - Use of a Barometer: A barometer is used to measure the atmospheric pressure. At sea level, the weight of the atmosphere is usually able to push the mercury up the tube.
Term
 What is the formula for Pressure?   A. P = F/A   B. P = A/F    C. P = A x F
Definition
 Answer is A. the formula for Pressure is P = F/A
Term
 States of Matter
Definition
 - Solids have a fixed shape/pattern and volume (lattice), they also have strong forces of attraction between the particles.  - Liquids have a fixed volume but changed shape depending on its container, these particles have weaker forces of attraction between them. No fixed pattern/lattice. - Gases have no fixed shape of volume, gases fill up their containers with almost no intermolecular forces between the particles as the particles are split far apart from each other.
Term
 What state of matter has the strongest forces of attraction between the particles?   A. Solid   B. Liquid   C. Gas
