Q: When a solution freezes, only what particles come together to form a solid phase, while the presence of solute particles interferes with that process? Read this paragraph and choose the correct option from the provided answers: The presence of solute particles has the opposite effect on the freezing point of a solution. When a solution freezes, only the solvent particles come together to form a solid phase, and the presence of solute particles interferes with that process. Therefore, for the liquid solvent to freeze, more energy must be removed from the solution, which lowers the temperature. Thus, solutions have lower freezing points than pure solvents do. This phenomenon is called freezing point depression. For every mole of particles in a liter of water, the freezing point decreases by about 1.9C. Both boiling point elevation and freezing point depression have practical uses. For example, solutions of water and ethylene glycol (C2H6O2) are used as coolants in automobile engines because the boiling point of such a solution is greater than 100C, the normal boiling point of water. In winter, salts like NaCl and CaCl2 are sprinkled on the ground to melt ice or keep ice from forming on roads and sidewalks. This is because the solution made by dissolving sodium chloride or calcium chloride in water has a lower freezing point than pure water, so the formation of ice is inhibited. Choices: - pigment - hydrogen - diluent - solvent A:
**Answer**
solvent

Q: Earth's magnetic north and south poles are not the same as what? Read this paragraph and choose the correct option from the provided answers: Earth has north and south magnetic poles like a bar magnet. Earth's magnetic poles are not the same as the geographic poles. Choices: - equatorial planes - geographic currents - geographic hemispheres - geographic poles A:
**Answer**
geographic poles

Q: The highest point of a wave is called? Read this paragraph and choose the correct option from the provided answers: Figure above also shows how the size of waves is measured. The highest point of a wave is the crest. The lowest point is the trough. The vertical distance between a crest and a trough is the height of the wave. Wave height is also called amplitude. The horizontal distance between two crests is the wavelength. Both amplitude and wavelength are measures of wave size. Choices: - surge - threshold - frequency - crest A:
**Answer**
crest
