Conduction…. Particles in s,l,g Mixing Hot and Cold Energy Transfer The transfer of energy (heat) from one particle to another by contact. NEED: touching and difference in temperature!! Find 5 places (this could be pictures, graphs, etc.) in your science notebook where conduction is probably occurring. Draw an arrow to them and label them “conduction”.
Equilibrium When a system is in balance – there is no more energy transfer occurring What would the equilibrium temperature be for 50 mL of 45 degree water mixed with 50 mL of 75 degree water? Label the equilibrium point on the three graphs in your science notebook…
