Explanation:

Question 2

Frost forms when water vapor (gas) in the air deposits directly to ice (solid) on a surface. For this, the air (with water vapor) should be warmer than the windshield (so vapor can cool) and the windshield should be colder (to allow deposition). So the correct pair is warmer air and colder windshield.

Deposition is a phase change where a substance transitions directly from the gaseous state to the solid state, skipping the liquid state. So the answer is solid.

Deposition involves a gas changing to a solid. So the states of matter involved are gas (initial) and solid (final). The options: a is solid (final), but the process involves gas (not listed? Wait, no—wait, the question is "states of matter involved in the process of deposition include". Deposition is gas → solid. So the states involved are gas (reactant) and solid (product). But the options: a is solids (product), but the process has gas (not an option? Wait, no, the options are a. solids, b. plasma, c. liquids, d. two of the above. Wait, no—wait, deposition is gas to solid. So the states involved are gas (which is not an option) and solid (option a). But wait, maybe the question is about the states present in the process (initial and final). But the options don't have gas. Wait, maybe I misread. Wait, the question is "States of matter involved in the process of deposition include". Deposition is gas → solid. So the states involved are gas (initial) and solid (final). But the options: a is solids (final state), but the process includes gas (which is not an option). Wait, maybe the question is phrased as the states that are part of the process (i.e., the phases involved: gas and solid). But the options: a is solids, b is plasma (not involved), c is liquids (not involved). Wait, no—maybe the question is wrong, or I misinterpret. Wait, no—deposition is gas to solid. So the states involved are gas (initial) and solid (final). But the options given: a. solids (final), but the process has gas (not an option). Wait, maybe the question is "states of matter involved" as in the phases that are part of the process (i.e., the two states: gas and solid). But the options don't have gas. Wait, maybe the options are miswritten. Wait, no—option d is "two of the above". Wait, no—wait, maybe the question is about the states that are present in the process (i.e., the substance is in gas and then becomes solid). But the options: a is solids (the final state), but the process involves gas (which is not an option). Wait, maybe the question is "states of matter involved" as in the phases that are part of the process (gas and solid). But the options: a is solids, b is plasma, c is liquids. So none of a, b, c alone, but d is "two of the above"—but which two? Wait, no—maybe I made a mistake. Wait, deposition is gas to solid. So the states involved are gas (initial) and solid (final). But the options don't have gas. Wait, maybe the question is "states of matter involved" as in the phases that the substance is in during the process. So the substance is in gas (before) and solid (after). But the options: a is solids (after), but the process has gas (before, not an option). Wait, maybe the question is incorrect, but based on the options, the only state involved in the process (as a product) is solid (option a), but the process also has gas (reactant). But the options don't have gas. Wait, maybe the question is "states of matter involved" as in the phases that are part of the process (i.e., the two states: gas and solid). But the options: a is solids, b is plasma, c is liquids. So none of a, b, c is gas. So maybe the answer is d? No, d is "two of the above". Wait, no—this is confusing. Wait, maybe the question is "states of matter involved" as in the phases that the substance can be in during deposition. But deposition is gas to solid. So the states involved are gas (initial) and solid (final). So the states are gas and solid. But the options: a is solids (final), but the process includes gas (not an option). Wait, maybe the question is wrong, but based on the opt…
