Solids Liquids and Gases Flashcards
State the formula for Density and what unit each component is measured in.
Formula: P = M/V (M / P x V)
M: Mass, P: Density, V: Volume
Units of measure: P: kg/m(cubed), M: m (cubed)
State the formula for Pressure and what unit each component is measured in.
Formula: F/ P x A (P = F/A)
F: Force, P: Pressure, A: Area
Units of measure: P: Pascals (Pa), 1Pa = 1N/m(squared)
List the conversion of units
Length:
1 kilometer = 1,000 meters
1 meter = 100 centimeters
1 centimeter = 10 millilitres
Mass:
1 Kilogram = 1,000 grams
1 gram = 1,000 milligrams
State the formula for Fluid Pressure and what unit each component is measured in.
Formula: Pressure difference = hight x density x g (P = h x d x g)
Units of measure: P: Pascals (Pa), H: m/cm, D: kg/m(cubed), G: 10 (always)
Changes of state
Solids:
- particles are very close together
- remain in a fixed regular lattice
- when heated particles vibrate and melt into a liquid
Liquids:
- particles vibrate fast enough to flow freely past one another
- remain relatively close contact though it’s not fixed nor predictable
- when heated particles gain enough energy to evaporate into a gas
Gases:
- particles are free to move past each other and remain spaced apart with a relative distance between them
- gas particles have the highest amount of kinetic energy among the states
State the definition of Brownian motion
The random, uncontrolled movement of particles in a fluid as they constantly collide with other molecule.
The conversion of Kelvin temperature to Celcius and vice versa.
Kelvin to Celcius = subtract 273
Celcius to Kelvin = Add 273
State the equation for the pressure law and the relationship between pressure and temperature (Kelvin).
Equation: P(1)/T(1) = P(2)/T(2)
Pressure is directly proportional to the temperature (kelvin) (P ∝ T (K))
State a brief summary of Boyle’s Law
Pressure is inversely proportional to volume.
Formular for Boyle’s law: P(1) x V(1) = P(2) x V(2)
