Answer the following question given this paragraph: A superheated liquid exists temporarily as liquid with a temperature above the normal boiling point of the liquid. When a supercooled liquid boils, the temperature drops as the liquid is converted to vapor. Conversely, a supercooled liquid exists temporarily as a liquid with a temperature lower than the normal melting point of the solid. As shown below, when a supercooled liquid crystallizes, the temperature increases as the liquid is converted to a solid. Q: When a supercooled liquid boils, the temperature drops as the liquid is converted to what? Choices: - carbon - solid - atoms - vapor A:
vapor

Answer the following question given this paragraph: A few elements, called metalloids, can conduct electricity, but not as well as metals. Examples include silicon and germanium in group 14. Both become better conductors at higher temperatures. These elements are called semiconductors. Q: A few elements, called what, can conduct electricity, but not as well as metals? Choices: - synthetics - gases - halogens - metalloids A:
metalloids

Answer the following question given this paragraph: Increasing or decreasing the temperature of a system at equilibrium is also a stress to the system. The equation for the Haber-Bosch process is written again below, this time as a thermochemical equation. Q: Increasing or decreasing the temperature of a system in what state acts as a stress to the system? Choices: - gaseous - nitrogen - liquid - equilibrium A:
equilibrium
