Question Answer
P1-Melting and Boiling You need to PUT IN ENERGY to BREAK INTERMOLECULAR BONDS. P1-Melting and Boiling Liquid=heat energy makes particles move faster.
P1-Melting and Boiling Solid=heat energy makes the particles vibrate faster. P1-Melting and Boiling When the intermolecular bonds break there is flat line on the graph, e.g. boiling, melting, freezing, condensing.
P1-Moving and storing heat SHC tells you HOW MUCH ENERGY stuff can store. P1-Melting and Boiling SLH is the ENERGY NEEDED to CHANGE STATE.
P1-conduction and convection in the home CONDUCTION occurs mainly in SOLIDS P1-conduction and convection in the home CONVECTION occurs mainly in LIQUIDS and GASES
P1-Moving and storing heat If there's a DIFFERENCE IN TEMPERATURE between two places, ENERGY WILL FLOW between them. P1-Moving and storing heat Energy tends to flow from hot objects to cooler ones.
P1-Moving and storing heat Absolute scale=cannot go below zero P1-Moving and storing heat The GREATER the DIFFERENCE in temperature, the FASTER the RATE OF COOLING.
P1-Moving and storing heat Temperature is a measure of KE of the particles in a substance. P1-Moving and storing heat The HOTTER something is the HIGHER AVERAGE KE.
