Question

which statements about water molecules are true? choose more than one answer.

• each has two hydrogen atoms and two oxygen atoms
• they form a crystal lattice when they freeze
• some condense directly from vapor into ice
• the air’s humidity affects the shape in which they freeze
• they form their most stable formation as a liquid

Explanation:

• Analyze each option:
• Option 1: A water molecule has 2 H and 1 O (formula \(H_2O\)), so this is false.
• Option 2: When water freezes (becomes ice), it forms a crystal lattice structure. This is true.
• Option 3: Deposition is the process where water vapor (gas) turns directly into ice (solid), so some water molecules can condense (deposit) directly from vapor to ice. This is true.
• Option 4: The shape of ice crystals (how water freezes) is affected by factors like temperature and humidity. So air's humidity can affect the freezing shape. This is true.
• Option 5: Water is most dense (and relatively stable) as a liquid, but "most stable formation" is a bit ambiguous, but compared to the others, the true ones are 2,3,4. Wait, re - check:
• Wait, the question says "choose more than one". Let's re - evaluate:
• Option 2: Ice has a crystal lattice - true.
• Option 3: Deposition (vapor to ice) occurs - true.
• Option 4: Humidity affects ice crystal shape (like snowflakes) - true.
• Option 5: Water is liquid at room temp, but is it the "most stable" formation? Ice is more stable at low temps, liquid at moderate. But the other options:
• Option 1 is wrong (\(H_2O\) has 2 H, 1 O).
• So correct options are the ones where statements are true: "They form a crystal lattice when they freeze", "Some condense directly from vapor into ice", "The air’s humidity affects the shape in which they freeze".

Answer:

B. They form a crystal lattice when they freeze, C. Some condense directly from vapor into ice, D. The air’s humidity affects the shape in which they freeze
