Which statement is incorrect when considering gases? 1. gas molecules are in constant, random motion at room temperature 2. the reason that gases are compressible is because the molecules of gas are very far apart compared to the size of the molecules 3. one reason why molecules of a gas fill a container is that there is no attraction between the molecules of the gas 4. the reason that a gas can be stored in a container is that the molecules no longer move when confined to a container.

4

Explanation:

For gases :

1. The motion of gases molecule is in random manner at the room temperature.

2.The distance between the gas molecule is more and that is why gas can be compress.

3.The attraction force between the gas molecule is negligible or we can say that there is no any force between the gas molecules.that is why gas can be filled in the container.But the motion of the gas molecule does not stop they are still moving inside the container but the space for movement become less.When a gas container heated then the container start to vibrate because the movement of the gas molecule.

So the option 4 is incorrect.

the answer to this question is 60 n
