Q: I have a new situation: Two sister cities were both situated on plate boundaries, close to volcanoes, on different continents. Red city was 10 miles from a volcano, while Tree city was 60 miles away. Red city experienced many earthquakes, Tree city few and far between. But I can use this background: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy creates an earthquake. During an earthquake the rocks usually move several centimeters or rarely as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ). What is an answer for this question: Which city experienced fewer rocks breaking?
A: Tree
Question: I have a new situation: John designed a hypothetical lever that would have ideal mechanical advantage. He labeled the lever as lever A. He then wanted to compare this lever with a real world lever, which he labeled as lever B. He intended to use these levers to increase force. But I can use this background: The Table above includes the ideal mechanical advantage of each class of lever. The mechanical advantage is the factor by which a machine changes the input force. The ideal mechanical advantage is the increase or decrease in force that would occur if there were no friction to overcome in the use of the machine. Because all machines must overcome some friction, the ideal mechanical advantage is always somewhat greater than the actual mechanical advantage of the machine as it is used in the real world. What is an answer for this question: Would lever B have higher or lower mechanical advantage than lever A?
Answer: lower
[Q]: I have a new situation: Mike was interested in the science behind polar compounds. To that end, he collected two compounds, compound A and compound B. Compound A was a polar compound, but compound B was a nonpolar compound. He then conducted two tests, case A and case B. In case A, he changed the state of a polar compound from solid to liquid. And, in case B, he changed the state of a nonpolar compound from solid to liquid. But I can use this background: Changes of state from solid to liquid and from liquid to gas occur when matter gains energy. The energy allows individual molecules to separate and move apart from one another. It takes more energy to bring about these changes of state for polar molecules. Although hydrogen bonds are weak, they add to the energy needed for molecules to move apart from one another, so it takes higher temperatures for these changes of state to occur in polar compounds. This explains why polar compounds have relatively high melting and boiling points. The Table below compares melting and boiling points for some polar and nonpolar covalent compounds. What is an answer for this question: Which test would need less energy, case A or case B?
****
[A]: case B
input: Please answer the following: I have a new situation: It is winter and Johnathan's car won't start, so he needs to walk to work. Even though it's sunny outside he's going to have to bundle up due to the cold temperature. In his closet there is a large black coat and a large white coat. He can't decide which coat to wear. But I can use this background: Light may transfer its energy to matter rather than being reflected or transmitted by matter. This is called absorption . When light is absorbed, the added energy increases the temperature of matter. If you get into a car that has been sitting in the sun all day, the seats and other parts of the car's interior may be almost too hot to touch, especially if they are black or very dark in color. That's because dark colors absorb most of the sunlight that strikes them. What is an answer for this question: Which coat will be less warm?
++++++++++
output: white coat
Please answer this: I have a new situation: Alexiev and Sabrina were enthusiastic chemistry students completing the first experiment of their new course. They both started the experiment with pure water, and had to perform different experimental protocols to make changes to the water. At the end of the experiment, both of them measured the concentration of hydronium ions present in their reaction mixtures. Alexiev had a high concentration of hydronium ions present, while Sabrina had a low concentration present in her mixture. But I can use this background: If a solution has a higher concentration of hydronium ions than pure water, it has a pH lower than 7. A solution with a pH lower than 7 is called an acid . As the hydronium ion concentration increases, the pH value decreases. Therefore, the more acidic a solution is, the lower its pH value is. Did you ever taste vinegar? Like other acids, it tastes sour. Stronger acids can be harmful to organisms. For example, stomach acid would eat through the stomach if it were not lined with a layer of mucus. Strong acids can also damage materials, even hard materials such as glass. What is an answer for this question: Which person's mixture, Alexiev's or Sabrina's, is more acidic at the end?
++++++++
Answer: Alexiev's
Question: I have a new situation: Two students studied chemistry. Nate studied alkanes, and Ben studied noble gasses. They both got an A later on. But I can use this background: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane with two carbon atoms. The chemical formulas and properties of methane, ethane, and other small alkanes are listed in the Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally boil and melt at higher temperatures. What is an answer for this question: Which student learned more about the melting point of alkanes?
Answer:
Nate
