Chemistry Exam 5 Notes Final Temperature of Water T 1 + T 2 = T final 2 If the volumes of water are equal then you can just add the temps of the volumes of water together and divide by the number of volumes of water and get the final temp. It is an average of all the temps. Transfer of Energy ∆T = T f - T i Calculate Calories Cal = mass x ∆T Energy always flows from hot to cold Energy is not created nor destroyed, it is only transferred-Law of Conservation of Energy When particles collide, energy is transferred from the faster moving (higher energy) particle to the slower moving (lower energy) particle. The faster moving particle gets

Unformatted text preview: slower and the slower moving particle speeds up. • Air particles are far apart unless compressed, water particles are closer together and can’t be compressed • When a volume of air is heated the air particles move faster, they collide more frequently, they move farther apart and occupy more space or expand. • When two objects have the same temperature they have the same kinetic energy and are at equilibrium • Equilibrium means that there is a balance • Heat energy is measured in calories • Temperature is the average kinetic energy and is measured in degrees Celsius...
