Structure of Matter and Kinetic Theory Flashcards
How do you differentiate between atoms and molecules?
Atoms are the smallest units of elements, while molecules are combinations of two or more atoms bonded together.
How does molecular theory explain Brownian motion?
Brownian motion is the random movement of particles suspended in a fluid, caused by their collision with fast-moving molecules in the fluid.
How does molecular theory explain diffusion?
Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, resulting from the random motion of molecules.
What are surface tension and capillarity?
Surface tension is the force that causes the surface of a liquid to contract and resist being broken.
Capillarity is the ability of a liquid to flow in narrow spaces without the assistance of external forces, often against gravity.
Q: What are adhesion and cohesion?
Adhesion is the attraction between different substances, like water and glass.
Cohesion is the attraction between like molecules, such as water molecules sticking together.
How does kinetic theory relate to Boyle’s law?
Boyle’s law states that the pressure of a gas is inversely proportional to its volume when temperature is constant.
How does kinetic theory explain Charles’ law?
Charles’ law states that the volume of a gas is directly proportional to its temperature when pressure is constant.
