What were the three essential ideas that we covered in the lesson?
Physical and chemical properties depend on the ways in which different atoms combine.
The mole makes it possible to correlate the number of particles with a mass that can be measured.
Mole ratios in chemical equations can be used to calculate reacting ratios by mass and gas volume
Gas volume and properties are calculated by using particles with a mass that can be measured.

Please explain in your own words what this graph is showing us. You have 2 minutes.
Temperature change versus energy input at fixed pressure as a solid substance is heated. The flat regions shown in red are where the state change is occurring, as heat energy is used to overcome the inter-particle forces. How do you interpret the graph at different stages?
Draw circles around the fluids.
