You are given a new situation: Scientists are observing two of the same gases at different temperatures. They are observing the speed of the particles in the gases to see how fast they are moving. Gas A has particles moving very quickly, but Gas B has particles that are hardly moving at all. and a hint : We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed. Please answer this question : Which gas is at a higher temperature?

Answer: Gas A

You are given a new situation: Tom and John are both pool owners. Tom prefers to use sodium bisulfate in his pool because he enjoys the smell. John, however, prefers using sodium carbonate in his pool because he believes it helps keep pests away. and a hint : We all enjoy a cool dip in a swimming pool on a hot day, but we may not realize the work needed to keep that water safe and healthy. The ideal pH for a swimming pool is around 7.2. The pH will change as a result of many factors. Adjustment can be accomplished with different chemicals depending on the tested pH. High pH can be lowered with liquid HCl (unsafe material) or sodium bisulfate. The bisulfate anion is a weak acid and can dissociate partially in solution. To increase pH, use sodium carbonate. The carbonate anion forms an equilibrium with protons that results in some formation of carbon dioxide. Please answer this question : Whose pool will have a lower pH?

Answer: Tom

You are given a new situation: Ronaldo and Jeff are two college roommates that have similar body structure and similar physical activity levels. Ronaldo is a nutrition enthusiast and eats a diet with appropriately low amounts of fat and cholesterol. Jeff, on the other hand, doesn't really care about nutrition at all. He eats whatever he wants, whenever he wants, and as a result he consumes a diet with an inappropriately high amount of fat and cholesterol. and a hint : Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. Please answer this question : Who is less likely to have increased blood lipid levels?
----
Answer:
Ronaldo
