This is the amount of energy required to change the state of 1kg of a substance with no change in temperature. Melting or freezing.
Faster-moving particles collide with the walls of a container more frequently and with more force, increasing the .
It is the sum of the (related to temperature) and the potential energy (related to state/distance between particles). Specific Latent Heat
Doing work on a gas (e.g., compressing it quickly) increases its internal energy and can cause a temperature rise. Typical Assessment Objectives
Increasing the temperature of a gas increases the kinetic energy of its particles.
Particles are in a fixed, regular arrangement and vibrate around fixed positions.
The module focuses on the structure of matter and how particles behave under different conditions. ) is defined as mass per unit volume. Formula:
Explaining macroscopic observations (like pressure) using microscopic particle behavior.
