Figure 11.9 I see that when I decrease the volume of the container, the pressure and temperature increase. When I increase the temperature, the pressure increases. When I increase the number of moles of the gas, the pressure increases. I can decrease the pressure when I decrease the temperature and increase the volume.Figure 11.26 I see that when I drop the block in the water a force equal to half the gravitational force on the object pushes up and the gravitational force decreases to ½, thus the object remains stationary in the water. When I drop the brick block in the water and it sinks, it only weighs half what it does out of the water, thanks to its buoyancy.

Figure 13.6 appears to be the same as 11.9

Figure 13.31 I see that when you heat the element the molecules vibrate and start to break apart and form a gas. When you cool the element, the molecules vibrate less and join together forming a liquid and then a solid.

Figure 13.35 I see that the larger the element and its repulsion forces, the more the potential energy increases when you bring them close together.

Very good.
