properties of matter

• pressure is the force applied per unit area
• specific heat capacity is the heat required to change the temperature of a substance by 1 degree
• lower specific heat capacity means less heat need to increase temperature
• temperature is the average kinetic energy of its particles
• specific latent heat is the heat energy required to change the state of 1kg of a substance without changing its temperature
• specific latent heat of fusion is solid and liquid and the specific latent heat of vaporisation is liquid and gas
• boyles law states the pressure is inversely proportional to the volume of a gas at constant temperature
• gay lussacs law is that pressure is directly proportional to temperature in kelvin
• charles law states volume is directly proportional to temperature in kelvin
• absolute zero means zero volume, zero temperature and zero pressure
• temp and volume kinetic model states that as temp increases particles move faster and colide more often- normally increasing pressure but for pressure to remain constant the number of collisions needs to decrease so we need to increase volume
