1. Describe the difference between the burning of a solid fuel and the burning of gaseous and liquid fuels.
2. Describe the thermal and chemical process that result in the ignition of, and during the burning of a solid.
3. Describe the hazards to people and property from fire.
4. Describe the most important toxic gases in smoke.
Describe the concept of limiting hazards and its role in fire protection. Visual emphasis such as bold, italicized, or underlined text should be used sparingly in order to maximize the prominence of key points. Each slide should address a single concept, and slides should follow a logical progression, each building on the other.
In a purity check for industrial diamonds, a 10.25 carat diamond is heated to 74.21 oC and immersed in 26.05 g of water in a constant pressure calorimeter.
