Question: I read this background article the other day: Further heating then adds energy to the liquid particles, increasing their speed, kinetic energy, and temperature. This is the second slope on the curve. Once the particles are energetic enough to completely break free of each other, they start to enter the gas phase. Boiling occurs at the second plateau of this curve, and the temperature at this point is referred to as the boiling point . Again, the added heat is being used to break up the interactions between particles instead of increasing their kinetic energy, so no temperature increase is observed until all particles are in the gas phase. Finally, adding even more energy will further speed up the gas particles, increasing the kinetic energy and temperature of the substance. I am facing a new situation today: Will is doing some testing with heat. He freezes some water in a cup then takes the ice cube and puts it into a pot. He places a thermometer on the ice cube and takes readings. To his surprise, the temperature on the thermometer is stable the entire time it's on the ice cube, Then the ice cube completely melts. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the temperature of pure liquid water ever go below its freezing point before freezing, yes or no?
Answer: no

Question: I read this background article the other day: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). I am facing a new situation today: Two groups of runners attended a 5k event downtown. Brown group warmed up properly before the race, but Red group did no such thing and suffered the consequences. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group didn't jog slowly to warm muscles?
Answer: Red

Question: I read this background article the other day: They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed. I am facing a new situation today: Bill and Larry did some research on fungi. Larry researched saprophytic fungi, while Bill researched parasitic fungi. They later exchanged findings. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which researcher learned less about fungi that live in other organisms?
Answer:
Larry
