Problem: You are given a new situation: The Jones family went jogging last Saturday. The weather was great for running, a bit chilly. The Brown family went jogging on Sunday and the weather was hot and humid, so it was tough for them, plus they forgot their Gatorade at home. and a hint : Millions of people in the world jog for exercise. For the most part, jogging can be a healthy way to stay fit. However, problems can also develop for those who jog in the heat. Excessive sweating can lead to electrolyte loss that could be life-threatening. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. If not treated, individuals can experience muscle weakness and increased heart rate (which could lead to a heart attack). Many sports drinks can be consumed to restore electrolytes quickly in the body. Please answer this question : Which family experienced more electrolyte loss?

A: Brown

Problem: You are given a new situation: Company A was a refinery and managed petroleum products. Another company, named company H, produced and distributed electricity using wind power. Both companies strive to be more efficient and to pollute less. and a hint : A major use for petroleum products is fuel for cars, trucks, airplanes, trains, and other vehicles. The chemical used are usually a mixture of compounds containing several carbon atoms in a chain. When the material is ignited, a massive amount of gas is created almost instantaneously. This increase in volume will move the pistons in an internal combustion engine to provide power. A jet plane works on a similar principle. Air comes into the front of the engine and mixes with the jet fuel. This mixture is ignited and the gases formed create a lot of pressure to push the plane forward. The idea can be seen even more clearly in the case of a rocket launch. The ignition of the fuel (either solid-state or liquid) creates gases produced under great pressure that pushes the rocket up. Please answer this question : Which company made less fuel for trains?

A: company H

Problem: You are given a new situation: James is going camping and decides to really live the experience. He brings only his tent and essentials and sets out into the woods. After pitching camp he remembers he needs to secure water. Luckily there is a stream nearby so he fill s a pot with water and brings it back to his camp. He starts a fire, placing the pot on top of it so the water can boil and a hint : 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. Please answer this question : Will the particles in water move slower or faster after increasing their temperature?

A: faster

Problem: You are given a new situation: Daniel drives a new car that uses catalytic converters. His best friend Kelvin however driving an older car. His car does not use any type of catalytic converter. They decide they want to go on a road trip together but dont know who's car they should take. and a hint : Catalytic converters in cars increase the rates of several important reactions. Unburned hydrocarbons can more easily be converted to carbon dioxide and water in the presence of a catalyst. Additionally, carbon monoxide (a harmful gas produced by incomplete combustion of fuel) is further oxidized to carbon dioxide, and nitrous oxide compounds (which contribute to smog and acid rain) are transformed back into nitrogen and oxygen gases. By passing car exhaust over these catalysts before their release into the air, the emissions from a combustion engine are made into much less harmful substances, resulting in a much cleaner atmosphere. Please answer this question : Will Kelvin buying a car like Daniel's increase or decrease the amount of pollution he creates while driving?

A:
decrease
