Energy, Heating & Gases

What is specific heat capacity? @ Energy needed to raise 1 kg by 1°C.

Equation for specific heat capacity. @ ΔE = mcΔθ

What does high specific heat capacity mean? @ More energy needed to heat it.

What is latent heat? @ Energy needed to change state without temperature change.

Why does temperature stay constant during change of state? @ Energy breaks/form bonds, not increase temperature.

Equation for specific latent heat. @ E = mL

What is specific latent heat? @ Energy to change state of 1 kg.

What is latent heat of fusion? @ Solid ↔ liquid.

What is latent heat of vaporisation? @ Liquid ↔ gas.

What happens on heating graph during change of state? @ Flat line (temperature constant).

What happens when gas is heated (volume constant)? @ Particles move faster and pressure increases.

Why does pressure increase when gas is heated? @ More frequent and forceful collisions.

What is pressure formula? @ p = F / A

What happens when gas volume increases? @ Pressure decreases.

Relationship between pressure and volume? @ Inverse relationship (pV = constant).

Why does reducing volume increase pressure? @ More collisions with container walls.

Why does doing work on a gas increase temperature? @ Work increases internal energy.

Example of doing work on a gas? @ Bike pump compressing air.
