Topic 3 - Particle Model of Matter Flashcards
1
Q
Density
A
Density = Mass ÷ Volume
ρ = m ÷ V
2
Q
Change in thermal energy
A
Change in thermal energy =
Mass × Specific Heat Capacity × temperature change
ΔE = m x c x Δt
3
Q
Thermal energy for a change in state
A
Thermal energy for a change in state = Mass × Specific Latent Heat
E = mL
4
Q
Constant in a gas
A
Constant = Pressure × volume
PV = constant
