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:
**Answer**
increase

Answer the following question given this paragraph: Interspecific competition often leads to extinction. The species that is less well adapted may get fewer of the resources that both species need. As a result, members of that species are less likely to survive, and the species may go extinct. Q: What kind of competition often leads to extinction because the species that is less well adapted gets fewer of the resources that both species need? Choices: - intraspecific competition - parasitism - mutualism - interspecific competition A:
**Answer**
interspecific competition
