Kinetic Theory of Matter Flashcards
What is Matter?
Matter is anything which has mass and takes up space
What is matter made of?
Matter is made up of tiny particles that are in constant motion because of the energy they contain.
What are the forces between particles
Forces of Attraction and Repulsion
Name the different particles.
Atom, Molecules and Ions
What determines the amount of kinetic energy held in a matter?
Temperature and the State of Matter (solid,liquid or gas)
What is an atom?
An atom is the smallest particle that cannot be broken down by chemical means.
What is a molecule?
A molecules is a particle containing two or more atoms. The atoms can be same or different.
What is an ion?
An ion is an atom or group of atoms with either a positive or negative charge.
What is Diffusion?
Diffusion is the spontaneous movement of particles of a substance from a region of higher concentration to a region of lower concentration, until the particles are evenly distributed
What is Osmosis?
Osmosis is the movement of water molecules (solvent) from a region of higher water concentration to a region of lower water concentration through a selectively permeable membrane.
What is the semi-permeable membrane?
The semi-permeable membrane has very tiny pores. These are big enough for water to pass through but too small for the solute particles to pass through.
What is Brownian Motion?
Brownian motion is the random movement of small particles in liquid or gases caused by bombardment of tiny particles that makes up the liquid or gas.
