Question
On a sheet of paper, write the word or phrase from the word Bank that completes each sentence. The volume of a gas greatly depends on its and pressure. When gas temperature increases, so does the of the particles. Gas pressure is created by the of gas particles. Pressure is the acting on a certain area. When the volume of a gas sample decreases, its increases. Unlike particles in liquids and solids, gas particles have great freedom of. On a sheet of paper, write the answer to each question. Contrast particles in solids and liquids with particles in gases. Why is atmospheric pressure higher at sea level than on mountaintops? Based on the kinetic model, describe how ideal gas particles act. A small container of perfume is opened in a classroom. Soon every student in the room smells the perfume. Explain this in terms of molecules.Explanation / Answer
Ok, I will answer from 1 to 6, if you want the other exercises please post another question and we wil gladly answer them:
1. The volume of a gas greatly depends on its_____________and pressure
ANSWER: Temperature, the volume of a gas will almost always change wih a variation on this two variables, if temperature increase and pressure decrease, the volume increase and if the temperature decrease and pressure increase, the volume decrease, if you want to know more this are greatly studied on Boyle´s, Charles and Gay-Lussac Laws
2. When gas temperature increase so does the _____________ of the particles.
ANSWER: Pressure, by Gay-Lussac´s Law we know that if the temperature from a gas increase so does its pressure, that ocurrs by the grater energy given to the particles, wich tend to move faster and create greater pressure on the sides of the container.
3. Gas pressure is created by the __________ of gas particles.
ANSWER: Collision, as the particles got close to eachother, they tend to collisionate between them, so they create pressure on the sides of the container.
4. Pressure is the ___________ acting on a certain area.
ANSWER: Force, explained by the formula: P=F/S
5. When the volume of a gas sample decrease, its____________ increase.
ANSWER: Kinetic energy, as the volume of a gas decrease , more molecules will strike a given area of the sides of the container per unit time, causing a greater pressure (also explained on 2).
6. Unlike particles on liquids and solids, gas particles have great freedom of __________.
ANSWER: Movement, as the gas state has almost no intermolecular bonds,so they can freely move.
