Effect of Pressure and Temperature on Volume

Flashcards covering the relationships between pressure, temperature, and volume, including molecular behavior and practical examples from the lecture notes.

Hot Air Balloon Expansion

When heated, temperature increases, volume increases, and density decreases, causing the balloon to rise while pressure remains same.

Relationship between Pressure and Volume

When the pressure increases, the volume decreases while the temperature remains constant, such as when compressing a bicycle tyre.

Relationship between Temperature and Pressure

When temperature increases, pressure increases while volume remains constant.

Kinetic Energy of Molecules

As temperature increases, this property of molecules increases, causing particles to move faster.

Molecular Collision Frequency

The result of increased kinetic energy where particles collide with the walls of the container frequently, leading to an increase in pressure.

Example of Temperature-Volume Change

Visualized in the notes through a change from $20^{\circ}C$ to $50^{\circ}C$ where a container expands from $V1$ to a larger volume.
