Problem: Given the question: Given the background: As Figure above shows, the distance between particles is much smaller for the solid and liquid states than for the gas state. In the solid state, particles are fixed in place, while particles are more free to move in the liquid and gas states. The particles in the solid and liquid states "stick together," but in the gas state, they move freely about the container. In general, it requires energy to separate individual particles. If we want to make a solid adopt a liquid form, we can add energy in the form of heat, increasing the temperature of the substance. Conversely, if we want to convert a substance from a gas to a liquid or from a liquid to a solid, we remove energy from the system and decrease the temperature. Pressure also plays an important role in changes of state, which will be discussed later on. We will study these difference in greater detail in the chapter States of Matter. and the situation: Thomas and Alexander are freshman students in an introductory chemistry laboratory course at their local college. In this week's experiment, both Thomas and Alexander will be starting their experiments with liquid water. They both follow different experimental protocols, and at the end of the experiment Thomas discovers ice in his reaction flask, while Alexander discovers steam in his reaction flask. Answer the following question: Which person created a substance with particles that have less distance between them than they did originally?
++++++++++++++++++++++++++++++++
The answer is:
Thomas

Problem: Given the question: Given the background: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. and the situation: Greg and Bobby are coworkers who are currently eating lunch together on their break. They haven't known each other very long and are having a casual conversation when Bobby mentions that he is a hemophiliac. Greg, unsure of what exactly that means, looks confused and taken aback. Bobby, noticing the bewilderment on Greg's face takes a moment to explain the details of his condition to Greg. Answer the following question: Which man will have less complications from a cut?
++++++++++++++++++++++++++++++++
The answer is:
Greg

Problem: Given the question: Given the background: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers. Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2] and the situation: High lake had a lot of fresh and salt water mixing, therefore presented layers of stratified water.The water was poor in nutrients.Low lake had no such problems and it was a very abundant and prolific fishing spot. Answer the following question: Which lake had fewer dissolved nutrients?
++++++++++++++++++++++++++++++++
The answer is:
High lake
