Question

vocabulary activity questions d atoms in solids are often more tightly packed than atoms in liquids, and have less space to move around freely. 4 imagine you sprayed perfume in the corner of a room. based on the passage, what is the concentration of perfume particles like in that corner, compared to in the rest of the room? a that corner has no concentration of perfume particles. b that corner has the same concentration of perfume particles as the rest of the room. c that corner has a lower concentration of perfume particles than the other corners of the room d that corner has a higher concentration of perfume particles than the other corners of the room 5 what is this passage mainly about? a matter and the properties it has in certain states b the process of diffusion how do we know? we can easily see liquids and solids around us, but most gases arent visible we cant see the air around us, but it is still made of atoms that constantly move around freely in space how can we tell? take a balloon, for example when we pump air into a balloon, it visibly inflates. that means that gaseous matter is filling the balloon and taking up space. the more air we blow into the balloon, the bigger it gets. therefore, we can observe the way gas moves around space in the same way, inflatable pool toys also fill with air so that they can float on water. when we fill the plastic shells with air, the toys take shape since air is less dense than water, the pool toys can rest on the water without sinking and then we can enjoy a sunny day while floating in a pool! moving atoms atoms are constantly moving however, atoms move at different

Explanation:

For Question 4:

When perfume is sprayed in a corner, the perfume particles (gas) will be more concentrated there initially compared to the rest of the room, as they haven't spread out yet.

For Question 6:

The passage first introduces atoms as the building blocks of matter, then explains how we can detect the presence of gaseous matter (atoms) through examples like balloons and pool toys, and finally mentions how atoms move differently in different states of matter. The core focus is on atoms (matter) and their properties in various states.

Answer:

1. D. That corner has a higher concentration of perfume particles than the other corners of the room.
2. A. matter and the properties it has in certain states
