p = F/A

p = ρgh

barometer: measures atmospheric pressure

manometer: measures/compares the difference in presssure of 2 fluids

- can be a gas or a liquid

-we are living in a fluid (air) at the moment

- fluids are able to flow or move around 

- surface area

-temperature

-wind

Evaporation happens at every temperature, while boiling always occurs at a fixed temperature - the boiling point of a liquid (100 degrees).

Evaporation only occurs at the surface of the liquid, while boiling can occur within the body of the liquid as bubbles of steam appear.

Gases expand the most.

Liquids do not expand as much as gases.

Solids expand the least when heated.

1. Liquid in glass (the liquid is usually mercury)

2. The clinical thermometer (used to measure temperature of humans)

3. Thermocouple thermometers (Consists of 2 wires of different materials)

C = E/mΔT

(E - energy, m - mass, T - degrees)

E = mL

(L - latent heat of fusion or evaporation, m - mass)

1. Sensitivity

2. Range

3. Linearity

4. Accuracy 

C = Q/mΔθ

(Q - thermal energy in Joules, m - mass in kg, Δθ - change in temperature in degrees, c - specific heat capacity in J/kg degrees C)

Q = mL

(Q - energy in Joules, m - mass in kg, L - latent heat in J/kg)

Sensitivity: amount of time needed for the thermometer to show the correct temperature

Precision: smallest possible temperature difference measured by the thermometer
