Q: What is the term for the amount of internal energy that the substance can store? Read this paragraph and choose the correct option from the provided answers: Heat capacity is the amount of internal energy that the substance can store. A large heat capacitance means the substance can store a lot of internal energy and thus the temperature changes slowly. Aluminum foil has a small heat capacitance and water has a large one. Choices: - mass capacity - temperature capacity - humidity capacity - heat capacity A:
(Answer)
heat capacity

Q: A binary molecular compound is made up of two of what? Read this paragraph and choose the correct option from the provided answers: A binary molecular compound is a molecular compound that is composed of two elements. The elements that combine to form binary molecular compounds are both nonmetal atoms. This contrasts with ionic compounds, which were formed from a metal ion and a nonmetal ion. Therefore, binary molecular compounds are different because ionic charges cannot be used to name them or to write their formulas. Another difference is that two nonmetal atoms will frequently combine with one another in a variety of ratios. Consider the elements nitrogen and oxygen. They combine to make several compounds including NO, NO 2 , and N 2 O. They all can't be called nitrogen oxide. How would someone know which one you were talking about? Each of the three compounds has very different properties and reactivity. A system to distinguish between compounds such as these is necessary. Choices: - compounds - cells - wafers - elements A:
(Answer)
elements

Q: What are the main organs for breathing in a mammal? Read this paragraph and choose the correct option from the provided answers: All mammals have lungs that are the main organs for breathing. Lung capacity has evolved to support the animal's activities. During inhalation, the lungs expand with air, and oxygen diffuses across the lung's surface and enters the bloodstream. During exhalation, the lungs expel air and lung volume decreases. In the next few sections, the process of human breathing will be explained. Choices: - gills - nostrils - intestines - lungs A:
(Answer)
lungs
