Answer the following question given this paragraph: A solute generally lowers the freezing point of a solvent, which is called freezing point depression. For example, spreading salt on an icy road melts the ice. Q: A solute generally does what to the freezing point of a solvent? Choices: - regulates it - raises it - increases it - lowers it A:
lowers it
Answer the following question given this paragraph: Q: In genetics, what do you call characteristics that are passed from a parent to child? Choices: - mutations - similarities - habits - traits A:
traits
Q: Answer the following question given this paragraph: Gas pressure is the result of collisions between gas particles and an object. Q: What two things collide to cause gas pressure? Choices: - gas particles and an electron - light particles and an object - gas particles and a wave - gas particles and an object A:
A: gas particles and an object
Question: Answer the following question given this paragraph: Molecular geometry is the three-dimensional arrangement of atoms in a molecule. The molecular geometry, or shape, of a molecule is an important factor that affects the physical and chemical properties of a compound. Those properties include melting and boiling points, solubility, density, and the types of chemical reactions that a compound undergoes. In this lesson, you will learn a technique to predict molecular geometry based on a molecule's Lewis electron dot structure. Q: Molecular geometry is the three-dimensional arrangement of atoms in a what? Choices: - genes - DNA - nucleus - molecule A:
Answer: molecule

Answer the following question given this paragraph: strong enough to keep the particles of substance together but not in place. Thus, the particles are free to move over each other but still remain in contact. In gases, the intermolecular interactions are weak enough that the individual particles are separated from each other in space. The kinetic theory of gases is a collection of statements that describe the fundamental behavior of all gases. Among other properties, gases exert a pressure on their container. Pressure is measured using units like pascal, bar, atmosphere, or mmHg (also called atorr). There are several simple relationships between the variables used to describe a quantity of gas. These relationships are called gas laws. Boyle's law relates the pressure and volume of a gas, while Charles's law relates the volume and absolute temperature of a gas. The combined gas law relates the volume, pressure, and absolute temperature of a gas sample. All of these gas laws allow us to understand the changing conditions of a gas. The ideal gas law relates the pressure, volume, amount, and absolute temperature of a gas under any conditions. These four variables are related to the ideal gas law constant, which is the proportionality constant used to calculate the conditions of a gas. Because the conditions of a gas can change, a set of benchmark conditions called standard temperature and pressure (STP) is defined. Standard temperature is 0C, and standard pressure is 1.00 atm. Q: What is measured using units pascal, bar, atmosphere or mmhg? Choices: - fuel - Muscle - push - pressure A:
**Answer**
pressure
