Answer the following question given this paragraph: Equal volumes of four different gases at the same temperature and pressure contain the same number of gaseous particles. Because the molar mass of each gas is different, the mass of each gas sample is different even though all contain 1 mol of gas. The relationships among the volume of a gas and its pressure, temperature, and amount are summarized in Figure 10.10 "The Empirically Determined Relationships among Pressure, Volume, Temperature, and Amount of a Gas". Volume increases with increasing temperature or amount but decreases with increasing pressure. Q: What does increased temperature cause the volume to do in a gas? Choices: - disappear - decrease - halve - increase A:
increase

Answer the following question given this paragraph: Rocks can break apart into smaller pieces in many ways. Ice wedging is common where water goes above and below its freezing point ( Figure below ). This can happen in winter in the mid-latitudes or in colder climates in summer. Ice wedging is common in mountainous regions like the Sierra Nevada pictured above. Q: When water goes above and below its freezing point, what rock-breaking phenomenon is common? Choices: - ice locking - ice inverting - ice crushing - ice wedging A:
ice wedging

Types of lipids include fats, oils, and phospholipids. Q: What are biochemical compounds that living things use to store energy and make cell membranes? Choices: - carbohydrates - proteins - nucleic acid - lipids A:
lipids
