Question: Which of the following gases is expected to behave most ideally?

Options:

Correct Answer: He

Solution:

Helium (He) is a noble gas with minimal intermolecular forces and small molecular size, making it behave most ideally.

Which of the following gases is expected to behave most ideally?

Which of the following gases is expected to behave most ideally?

Step 1: Understand what an ideal gas is. An ideal gas is a theoretical gas that follows the gas laws perfectly and has no intermolecular forces.
Step 2: Identify the characteristics of gases that behave ideally. These include small molecular size and minimal intermolecular forces.
Step 3: Look at the options given in the question. Identify which gas is a noble gas, as noble gases typically have minimal intermolecular forces.
Step 4: Among the options, select Helium (He) because it is a noble gas with very small size and weak intermolecular forces.
Step 5: Conclude that Helium (He) is expected to behave most ideally compared to other gases.
