1 When the temperature of a metal ring increases, does the hole become larger? Smaller? Or remain the same size? 1. Larger2. Smaller 3. Remain the same size

2 When the temperature of a metal ring increases, does the hole become larger? Smaller? Or remain the same size?

3 When the temperature of the piece of metal is increased and the metal expands, will the gap between the ends become narrower, or wider, or remain unchanged? 1. Narrower 2. Wider 3. Remain unchanged

4 When the temperature of the piece of metal is increased and the metal expands, will the gap between the ends become narrower, or wider, or remain unchanged?

5 Water molecules in ice link together to form an open-spaced structure. The open pockets in the structure are what makes ice less dense than water, which is why ice floats on water. To be sure you interpret this correctly, answer this: Whats inside the open pockets? 1. Air 2. Water vapor 3. Nothing
