Exploring Science 7© Pearson Education Limited Pressure in a container full of gas is caused by: Aparticles sticking to the walls. Bparticles bumping into the walls. Cparticles sticking to each other. Dparticles falling to the bottom of the container. Quick Quiz 7Ge

Exploring Science 7© Pearson Education Limited You can increase the pressure in a container full of gas by: Amaking the container smaller. Bmaking the container bigger. Ccooling the gas. Dtaking some of the gas out. Quick Quiz 7Ge

Exploring Science 7© Pearson Education Limited If you put more gas into a container the pressure increases because: Athe particles all cool down. Bthere is more space for the particles to move around. Cmore particles fall to the bottom of the container. Dthere are more particles, so there are more collisions with the wall. Quick Quiz 7Ge

Exploring Science 7© Pearson Education Limited The air is being sucked out of this bottle. Why is it collapsing? Quick Quiz 7Ge AThere is more air pressure inside than outside. BThere is more air pressure outside than inside. CThere are more particles inside it. DAir particles are sticking to the walls and pulling them in.
