In the provided example, the volume of gas at 2 atm is calculated to be _____. The ____ of a gas is directly proportional to the number of moles at constant temperature and pressure, according to Avogadro’s Law. Avogadro’s Law is key to understanding how ____ behavior is affected by changes in moles, volume, temperature, and pressure.

Basic Answer

Correct answer:

  1. volume
  2. volume
  3. gas

Analyze:

  1. Keyword/sentence analysis: The first blank refers to the volume of gas at a specific pressure (2 atm). The second blank relates to a fundamental property of gases that is directly proportional to the number of moles. The third blank discusses the general behavior of gases in relation to Avogadro’s Law.
  2. Contextual relationship: The context of the question revolves around gas laws, specifically Avogadro’s Law, which states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. This indicates that volume is a key factor in gas behavior.
  3. The answer derivation process:
    • For the first blank, since the question mentions calculating the volume of gas at 2 atm, “volume” is the logical answer.
    • For the second blank, Avogadro’s Law states that the volume of a gas is directly proportional to the number of moles, so “volume” fits here as well.
    • For the third blank, the word “gas” is appropriate as it refers to the type of substance whose behavior is being analyzed under the conditions described by Avogadro’s Law.

Point of knowledge

  1. Relevant Knowledge Point 1: Avogadro’s Law states that at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of the gas.
  2. Relevant Knowledge Point 2: The ideal gas law (PV=nRT) incorporates pressure (P), volume (V), number of moles (n), the ideal gas constant (R), and temperature (T), illustrating the relationships between these variables.

Error-prone tips

  1. Error-prone content 1 and reasons: Students might confuse the relationship between pressure and volume, leading them to think that pressure is directly proportional to the number of moles instead of volume. Remember, Avogadro’s Law specifically addresses volume and moles.
  2. Error-prone content 2 and reasons: Some may incorrectly apply the concepts of other gas laws (like Boyle’s or Charles’s Law) instead of focusing on Avogadro’s Law. It’s important to distinguish which law applies to the situation being analyzed.
