Doing work on a gas (e.g., compressing it quickly) increases its internal energy and can cause a temperature rise. Typical Assessment Objectives
Explaining macroscopic observations (like pressure) using microscopic particle behavior.
Measuring the density of regular and irregular solids (using displacement cans). [KS] KS4 SP14.rar
If the .rar file you are referring to is a study pack or assessment resource, the following write-up serves as a comprehensive summary of the core concepts generally included in this module. Core Concepts of KS4 SP14 (Particle Model)
This is the amount of energy required to change the state of 1kg of a substance with no change in temperature. Melting or freezing. Doing work on a gas (e
Solids are generally the most dense, followed by liquids, then gases.
Faster-moving particles collide with the walls of a container more frequently and with more force, increasing the . If the
Increasing the temperature of a gas increases the kinetic energy of its particles.
