Chromatography is used to dissolve a mixture

Chromatography is used to separate and help identify substances in a mixture.

Gas pressure is caused by gravity pulling the gas down.

Gas pressure is caused by gas particles colliding with the walls of the container.

100

Gas particles are easy to compress because the particles themselves are very small

Gases are easy to compress because there are large spaces between the particles.

If an ink separates into three spots, the ink must contain three different elements

If an ink separates into three spots, the ink must contain three different elements

200

When you put more air into a balloon, the pressure decreases because the particles have more space

Adding more particles causes more collisions with the walls, increasing the pressure.

200

When you compress a gas, the particles become smaller.

The particles stay the same size; the spaces between them become smaller.

300

All substances in a chromatography experiment travel the same distance up the paper.

Different substances travel different distances because they have different interactions with the paper and solvent.

300

Liquid pressure only acts downwards because gravity pulls the liquid down.

Liquid particles move and collide in different directions, so liquid pressure acts in all directions.

Intermingling means that two different types of particles turn into one type of particle.

Intermingling means different types of particles mix/spread amongst each other while remaining the same particles.
