CM 8001 – AE3
Question 1: a. Exothermic. A charcoal briquette releases heat as it burns. b. Endothermic. Water absorbs the heat necessary for evaporation from your skin, and your skin feels cooler. c. Endothermic. Ice absorbs the necessary heat to melt from the environment. Question 2: Consider a natural gas (methane) explosion: CH4 + 2 O2 -> CO2 + 2 H2O The bond… Read more →
