Mass
Porosity refers to the amount of empty space that is between particles of material. When something has a low porosity, it does not have much of this space between its particles.
Particles in a liquid have only a small amount of space between each other. They have more energy then solid particles but less energy than gas particles. Particles in liquid roll over each other this is what causes water to flow.
semi-permeable
crushing particles of solute
You are putting more air particles in the same amount of space
As the space changes between the particles, so does the state of matter.
when the temperature is warm, the particles move faster and the gas is expanding and pushing on the walls of the item, like for example, a NYPD float balloon. If the gas expands too much, the balloon will explode
Mass
The amount of space that gas particles can take up is the size of the container, but the amount between them also is determined by the amount of space the gas takes up.
Can the amount the balloon fills up be controlled by amount of baking soda
Can the amount the balloon fills up be controlled by amount of baking soda
a particle of hellium is small enough to fit in between the molecules of latex (or whatever the balloon is made of) and eventually leaks out due to diffusion. If the environment the balloon is in has the same amount of hellium in it as the balloon, it won't deflate.
PV/NrT, pressure(volume)/amount(constant)(temperature). When your temperature, volume, and pressure are all the same, you get the same number of particles. This is avogadros hypothesis. Let's say that you have to balloons. They have the same temperature, volume, and pressure. If you weigh the gases in the balloon, you will find that there is the same amount of particles. In fact Dalton did this was able to find out the amount of particles (atoms) by the mass of objects.
high porosity
Porosity refers to the amount of empty space that is between particles of material. When something has a low porosity, it does not have much of this space between its particles.
Pipette can hold a small amount of liquid but a graduate cylinder can hold more and its good for accuracy.
