Physics - P1 - Equations

density

ρ = m/v

---

density = mass / volume

specific heat capacity (change in internal energy)

△E = mc△t

---

change in internal energy (J) = mass (kg) x specific heat capacity (J/kg*C) x temperature change (*C)

specific latent heat (energy required for state change)

E = mL

---

energy required (J) = mass (kg) x specific latent heat (J/kg)

pressure

P = F/A

---

Pressure (Pa) = force (N) / area (m²)

pressure in a liquid

p=hpg

---

pressure in a liquid (Pa) = height of liquid column (m) x density (kg/m²) x gravitational field strength (N/kg)

pressure and volume relationship

P₁V₁ = P₂V₂

PV = constant
