Explain what happens to the particles in a substance when it is heated.
When a substance is heated, the particles gain kinetic energy, causing them to move faster. In solids, they vibrate more; in liquids, they move more freely; and in gases, they move more rapidly and spread apart.
What is the difference between boiling and evaporation?
Boiling occurs at a specific temperature throughout the liquid, where particles throughout the liquid gain enough energy to change to gas. Evaporation, on the other hand, occurs at the surface of a liquid at any temperature, as some particles at the surface gain enough energy to escape into the air.
What is meant by 'changing state'?
Changing state refers to the process where a substance transitions between solid, liquid, or gas, for example, melting, freezing, condensation, or boiling. This involves changes in the arrangement and energy of the particles.
How does the particle model explain the pressure exerted by gases?
The particle model explains that gas pressure is caused by the collisions of gas particles with the walls of a container. The faster the particles move and the more collisions there are, the higher the pressure.
What happens to the volume of a gas when its temperature is increased at constant pressure?
According to Charles' Law, when the temperature of a gas is increased at constant pressure, the volume increases, as the particles move faster and need more space.
How does the particle model explain the difference between a solid, liquid, and gas?
In solids, particles are closely packed and only vibrate. In liquids, particles are close but can move around each other. In gases, particles are far apart and move rapidly in all directions.
What is meant by 'latent heat' in terms of the particle model?
Latent heat refers to the energy required to change the state of a substance without changing its temperature. During a phase change, the energy is used to overcome the forces between particles rather than increasing their kinetic energy.
What happens to the speed of the particles as a substance goes from solid to liquid?
As a substance goes from solid to liquid, the particles gain energy, move faster, and can slide past each other, allowing the substance to flow.
What is the relationship between pressure and volume in a gas at constant temperature?
According to Boyle’s Law, the pressure of a gas is inversely proportional to its volume at a constant temperature. As the volume decreases, the pressure increases, and vice versa.
How does the particle model explain the expansion of substances when heated?
The particle model explains that when substances are heated, the particles gain kinetic energy, causing them to move faster and push further apart, resulting in expansion.
