Matter
This is anything that has matter and takes up space
What is matter?
The ability to do work
What is energy?
The substance doing the dissolving
The attraction of other substances besides water in a process
What is adhesion?
The law of Conservation of Mass and Energy
What is "Matter and energy cannot be created or destroyed"?
The smallest possible particle of an element
What is an atom?
Four types of energy
What is
Mechanical energy (kinetic and potential)
Acoustic energy
Light energy
Thermal energy
Electrical energy
Chemical energy
Energy is released in this reaction
What is exothermic?
The attraction of water molecules to each other
What is cohesion?
The change in a substance that does not change the identity of the substance
What is a physical change?
A pure substance made of only one kind of atom
What is an element?
In this reaction, the products have more energy than the reactants because energy is absorbed from the surroundings to drive the reaction.
What is an endothermic reaction?
The process by which particles in solution are evenly distributed throughout the solvent by Brownian motion
What is diffusion?
Molecules that are found in and make up living things
What are biomolecules?
The tendency that particles have to move around and spread out
What is Brownian motion?
A pure substance made from two or more elements that are chemically combined
What is a compound?
A measurement of the average kinetic energy of the particles within a substance
What is temperature?
A substance that speeds up a chemical reaction by providing an alternate pathway that requires less activation energy.
What is a catalyst?
A covalently bonded compound containing the element carbon
What is an organic compound?
The salt in a solution
What is a solute?
A particle consisting of two or more atoms covalently bonded together
What is a molecule?
In this reaction, the reactants have more energy than the products
What is an exothermic reaction?
In living organisms, these are biological catalysts.
What are enzymes?
Four examples of biomolecules
What are lipids, carbohydrates, proteins, and nucleic acids?
Water has a negatively charged side and positively charged side which makes it this type of molecule.
What is polar?
