Thermochemistry Chapter 10

Energy-ability to do work or produce heat Ex: Cars need energy to run. People need energy to live.

Energy Classifications Potential energy-energy due to position or composition Kinetic energy-energy due to motion

Measuring Energy Changes calorie(c)-amount of energy required to raise the temperature of one gram of water by one Celsius degree. (Food you eat is measured in Kilocalories which is abbreviated C). Joule (J)-the SI unit of energy 1 c=4.184J

1st Law of Thermodynamics The law of conservation of energy states that energy cannot be created or destroyed. Therefore, the total energy in a system is conserved.

What’s the difference between energy and heat?

Temperature-measures the molecular motions of the particles Heat(Enthalpy)-the flow of energy due to temperature difference **You can have temperature without having heat

Exothermic reactions-energy flows out of the system. Endothermic reactions-energy flows into a system. q or H represents heat

Label as exo or endo Your hand gets cold when you touch ice. Ice cream melts. Propane is burning in a propane torch. Water drops on your skin evaporate after swimming.

Answers Exo hand+icewater+heat (your hand feels cold because heat is leaving, your hand has less energy after it touches the ice) 2) endo Ice cream+heat  melted ice cream (the melted ice cream has more energy so heat must have been added to the system)

3) exo- propane gas  heat (heat is released) 4) endo water+body heatevaporation (in order for something to evaporate heat has to be added)

Hess’s Law Hess’s Law-the overall enthalpy change in a reaction is equal to the sum of enthalpy changes for the individual steps in the process

Entropy Entropy-a measure of the disorder or randomness Abbreviated with ∆S If you take a deck of cards and drop them on the floor, that would have high entropy. If you buy a new deck, that would have low entropy.

2nd Law of Thermodynamics The entropy of the universe is always increasing Processes in nature are driven toward lowest enthalpy and highest entropy
