Sp14.rar: [ks] Ks4

Doing work on a gas (e.g., compressing it quickly) increases its internal energy and can cause a temperature rise. Typical Assessment Objectives

Energy is used to break intermolecular bonds rather than increasing temperature during melting or boiling. The total energy stored by particles in a system.

Boiling or condensing. Formula: (Energy = mass Specific Latent Heat). Gas Pressure and Temperature [KS] KS4 SP14.rar

Applying the density and latent heat formulas correctly.

Particles are close together but can move past each other in an irregular arrangement. Doing work on a gas (e

Faster-moving particles collide with the walls of a container more frequently and with more force, increasing the .

Particles are far apart and move randomly at high speeds. Changes of State Physical changes (reversible) rather than chemical changes. Mass is conserved during a change of state. Boiling or condensing

It is the sum of the (related to temperature) and the potential energy (related to state/distance between particles). Specific Latent Heat
