Answer:
Explanation:
density is the amount of weight/mass packed into a specific volume of material so i believe that is right
Explanation:
The kinetic theory of gases is basically used to explain the behavior of gases.
Some of the assumptions of the theory is as follow:
- A gas is composed of large number of identical molecules at different speeds.
- The space occupied by the gas molecules themselves are negligible compared to the volume of the space they occupy.
- The molecules are independent of each other and the force of attraction and repulsion between them are negligible.
- The molecules collide elastically with one another and with the walls of the container.
- The temperature of gas is a measure of their average kinetic energy.

So I haven’t got time to answer all of it for you but the id you look at the picture of the periodic table I’ve added the top number in the red boxes are the groups and the period is how many elements down from the top it is (remember that the hydrogen and helium make up period ONE) so remember to include them when counting the elements as you go down the table
