Answer:

Across

1. loosely (Liquids have molecules less tightly packed than solids, so "loosely" fits as they are more loosely packed than solids? Wait, no—wait, solids are tightly packed, liquids are more loosely than solids? Wait, no, actually solids are tightly packed, liquids are less tightly (more loosely) than solids? Wait, the sentence is "In a liquid, molecules are more ____ packed than in a solid." So since solids are tightly packed, liquids are more loosely packed. So word: loosely.
2. shape (Liquids don’t have a definite shape, they take the container’s shape. So "shape".
3. Molecules (In solids, molecules are very close together. So "Molecules".
4. volume (Liquids have a definite volume. So "volume".
5. definite (Solids have a definite shape and definite volume. So "definite".
6. sublimation (Some solids change directly to gas: sublimation. The word bank has "sublimation".
7. container (A liquid takes the shape of its container. So "container".

Down

1. boiling points (Liquids change to gases at boiling points. So "boiling points".
2. heated (Solids change to liquids when heated (melting). So "heated".
3. space (When poured, liquid takes same amount of space (volume, but "space" here? Wait, word bank has "space"? Wait, word bank: "volume" is there. Wait, "takes up the same amount of volume"—but word bank has "volume" and "space". Wait, the sentence: "When a liquid is poured from one container into another, it takes up the same amount of ____." So it’s volume. Wait, word bank has "volume". Wait, maybe I misread. Let me check word bank: "volume" is there. So 5. volume? Wait, no, the word bank has "space" too. Wait, maybe "space" is not right. Wait, liquids have definite volume, so when poured, volume remains same. So "volume". But let’s check word bank: "volume" is an option. So 5. volume? Wait, the original word bank: "volume" is there. So 5. volume.
4. Liquids (Liquids change shape (take container’s shape). So "Liquids".
5. solid (Molecules in liquid move more than in solid. So "solid".

Let’s list all answers with their numbers:

• Across 2: loosely
• Across 3: shape
• Across 7: Molecules
• Across 9: volume
• Across 10: definite
• Across 11: sublimation
• Across 12: container
• Down 1: boiling points
• Down 4: heated
• Down 5: volume
• Down 6: Liquids
• Down 8: solid

(Note: For the crossword grid, you’d place each word in the corresponding numbered boxes. For example, Across 2 is a 7-letter word? Wait, "loosely" is 7 letters. Let’s check lengths:

• Across 2: 7 letters → "loosely" (7)
• Across 3: 5 letters → "shape" (5)
• Across 7: 8 letters? Wait, "Molecules" is 8 letters. Let’s check the grid: Across 7 is a horizontal entry. Let’s assume the grid’s letter counts match. Similarly, Down 1: "boiling points" → but wait, the word bank has "boiling points" as a phrase? Wait, the word bank lists "boiling points" (two words) but the crossword boxes—maybe it’s a single word? Wait, no, maybe I made a mistake. Wait, the word bank: "boiling points" is a phrase, but maybe the crossword uses single words. Wait, no, the Down 1: "Liquids change to gases when they reach their ____." So "boiling point" (singular)? But word bank has "boiling points". Maybe it’s "boiling points" (plural). Alternatively, maybe "boiling point" but word bank has "boiling points". So proceed with word bank.

Similarly, Down 4: "Some solids change into liquids when ____." → "heated" (5 letters? Let’s check grid: Down 4’s box length. If it’s 5 letters, "heated" is 5. Yes.

Down 5: "takes up the same amount of ____." → "volume" (6 letters? Let’s check. If the box is 6 letters, "volume" is 6. Yes.

Down 6: "____ change shape." → "Liquids" (7 letters? Let’s check. If the box is 7 letters, "Liquids" is 7. Yes.

Down 8: "molecules in a ____." → "solid" (5 letters. Yes.

So final answers (placing in grid):

• Across 2: loosely
• Across 3: shape
• Across 7: Molecules
• Across 9: volume
• Across 10: definite
• Across 11: sublimation
• Across 12: container
• Down 1: boiling points
• Down 4: heated
• Down 5: volume
• Down 6: Liquids
• Down 8: solid
