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.  Now, 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.  Answer this question please: Which test would need higher temperature, case A or case B?
Ans: case A

I can use this background: Pressures are given in a multitude of units. We've already discussed Pascals, and we know that another unit for pressure is the atmosphere (1 atm = 101.3 x 10 5 Pa). The third commonly used pressure unit is the torr (symbol Torr). 760 torr is 1 atm, but 1 torr is also the increase in pressure necessary to cause liquid mercury to rise by 1 mm. For that reason, torr is also commonly referred to as "millimeters mercury." Another pressure unit commonly used in our everyday world is psi, or pounds per square inch, though neither psi nor torr are SI units.  Now, I have a new situation: Mike is studying for his physics exam. He realizes that the best way to learn physics is to solve problems. To that end, he needs to to convert pressure of objects from one unit to another. In one problem, four scenarios are given for the same object, scenario A, scenario B, scenario C, and scenario D. In scenario A the pressure is given in Pascals. In scenario B the pressure is given in the atm. In scenario C the pressure is given in torr. Lastly, in scenario D the pressure is given in psi.  Answer this question please: In which scenario pound and inch are factors in devising the unit, scenario C or scenario D?
Ans: scenario D

I can use this background: Type 2 diabetes is much more common than type 1 diabetes. Type 2 diabetes occurs when body cells no longer respond normally to insulin. The pancreas still makes insulin, but the cells of the body can’t use it. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes. This type of diabetes usually develops in adulthood. However, it is becoming more common in teens and children because more young people are overweight now than ever before.  Now, I have a new situation: Justin and his sister Samantha recently had a visit with their doctors to see how their health was doing. Justin was told that he weighs too much and his blood pressure is higher than normal. Samantha was told she is at an appropriate weight and her blood pressure is normal.  Answer this question please: Who is at a lower risk for developing type 2 diabetes?
Ans: Samantha

I can use this background: Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and Epstein–Barr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years.  Now, I have a new situation: Two cousins both have chronic viral infections. Tim has Kaposi's sarcoma-associated herpesvirus, while Nate has the Epstein–Barr virus.  Answer this question please: Which cousin has a lower chance of  developing Kaposi's sarcoma?

Ans: Nate
