Problem: Given the question: Given the background: Continued heating of the water after the ice has completely melted will now increase the kinetic energy of the liquid molecules and the temperature will rise. Assuming that the atmospheric pressure is standard, the temperature will rise steadily until it reaches 100C. At this point, the added energy from the heat will cause the liquid to begin to vaporize. As with the previous state change, the temperature will remain at 100C while the water molecules are going from the liquid to the gas or vapor state. Once all the liquid has completely boiled away, continued heating of the steam (remember the container is closed) will increase its temperature above 100C. and the situation: Chris decides he is going to make some pasta for dinner tonight. He gets a large pot, fills it with water and puts it on the stove. He sets the stove to 99 degrees C. After a while he comes back and sees that the water is hot but it isnt boiling. He sets the temperature to 100 degrees C and walks away. He forgets he was heating up the water and comes back to an empty pot. The water got too hot, turned into is gas form, steam, leaving an empty pot Answer the following question: Which is hotter, water in liquid form or water in gas form?
++++++++++++++++++++++++++++++++
The answer is:
gas

Problem: Given the question: Given the background: Turner et al (2006) derived crash prediction models for this report's predecessor and found a pronounced 'safety in numbers' effect in the models. Using the crash prediction model for mid-block locations, generic motorist and cyclist volumes can be used to demonstrate the impacts on the expected crash rate of varying motor vehicle and cycle volumes. As shown in figure 2.20, an increase in the proportion of cyclists to the overall traffic volume causes an increase in expected crashes at mid-block locations, but the crash rate increases at a decreasing rate. That is to say, the crash rate per cyclist goes down as the cycle volume increases. and the situation: Berg village and Hill village are renowned for the high number of cyclists living there. Berg village dealt with many traffic casualties because of narrower streets and lanes, While Hill village had wide streets, more traffic signals and a greater number of cyclists. Answer the following question: Which village had a higher crash per cyclist ratio?
++++++++++++++++++++++++++++++++
The answer is:
Berg

Problem: Given the question: Given the background: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. and the situation: Two identical chemical compounds are both in beakers on top of burners in a laboratory. Beaker A is sitting on top of a burner that is set to a low temperature, and Beaker X is on a burner with a high temperature. Ken, the scientist studying these compounds, is closely monitoring the chemicals to see what type of changes occur. Answer the following question: Are the particles in Beaker A more or less likely to bump into each other than the particles in Beaker X?
++++++++++++++++++++++++++++++++
The answer is:
less
