Equal volume of all gases contain equal number of atoms at same temperature and pressure. This statement is

Options

A. In accordance with Dalton's atomic theory and is known as Berzelius Hypothesis
B. Not in accordance with Dalton's atomic theory and is known as Avogadro's Hypothesis
C. Not in accordance with Dalton's atomic theory and is known as Berzelius Hypothesis
D. In accordance with Dalton's atomic theory and is known as Avogadro's Hypothesis

Answer

To solve the question regarding the statement "Equal volume of all gases contain equal number of atoms at the same temperature and pressure," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Statement**:
- The statement suggests that if you have equal volumes of different gases at the same temperature and pressure, they will contain the same number of atoms.

2. **Referencing Avogadro's Hypothesis**:
- Avogadro's Hypothesis states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. This implies that the number of molecules is directly proportional to the volume when temperature and pressure are constant.

3. **Relating Molecules to Atoms**:
- While Avogadro's Hypothesis specifically mentions molecules, it can be inferred that if we consider diatomic or polyatomic gases, the number of atoms can vary. For example, one molecule of O₂ has 2 atoms, while one molecule of N₂ has 2 atoms as well. Therefore, the statement is not universally true for all gases.

4. **Evaluating the Options**:
- The question likely provides multiple-choice options. We need to determine which option correctly identifies the statement's relation to known theories.
- The first option mentions Dalton's Atomic Theory and Berzelius Hypothesis, which are not directly related to the statement.
- The second option correctly identifies that the statement is in accordance with Avogadro's Hypothesis.

5. **Conclusion**:
- The correct answer is that the statement is in accordance with Avogadro's Hypothesis, making the second option the correct choice.
