Why solids and liquids cannot be compressed (squashed into a smaller volume) ?
The particles are touching each other with a lot of spaces between them.
The particles are touching each other with no spaces between them.
The particles are spreading out.
Liquids and solids are special molecules with different compression rates.
What happens when steam in the bathroom hits a cold surface?
Some of the heat energy of the particles is transferred to the mirror so the particles have more energy and condense to form a liquid.
Some of the heat energy of the particles is transferred to the mirror so the particles have less energy and melt to form a liquid.
Some of the heat energy of the particles is transferred to the mirror so the particles have less energy and condense to form a liquid.
Why is diffusion faster in a gas than in a liquid?
Gases have small intermolecular space and less kinetic energy
Liquids have large intermolecular space and more kinetic energy
Liquids have small intermolecular space and less kinetic energy
Gases have large intermolecular space and more kinetic energy
If a gas is forced into a small space what happens to the pressure?
The space collide.
The pressure increases.
The pressure decreases.
The space explode.
How oxygen diffuses from an air sac into the blood?
Some of the oxygen molecules inside the air sacs will bounce into the wall of the air sac and capillary and travel through to the other side.
Some of the carbon dioxide molecules inside the bronchus will bounce into the wall of the bronchioles and veins and travel through to the other side.
Some of the carbon dioxide molecules inside the air sacs will bounce into the wall of the air sac and capillary and travel through to the other side.
Why smokers find it very hard to give up smoking?
Particulates are tiny particles of soot and other substances. They get into the lungs and damage the cells.
Tar in cigarette smoke causes cancer. Cancer is a disease in which some cells divide uncontrollably, forming a lump called a tumour.
Nicotine is an addictive drug. It affects the brain, so that a person who has used it finds it very difficult to stop.
Carbon monoxide is an invisible gas. It combines with the haemoglobin inside red blood cells.
There are some components of cigarette smoke that especially affects athletes, as it prevents their muscles from obtaining the oxygen necessary to exert effort during a competition. Which?
Nicotine and Tar
Tar and Oxygen
Carbon Monoxide and Particulates
Particulate and Cancer
You can buy bottled gas to use for cooking. This gas is squeezed into a small space and is sold in containers that are very strong. Explain why the containers need to be very strong.
The container must be very strong to withstand the heat.
The container must be very strong to withstand the pressure.
The container must be very strong to withstand the diffusion.
Why is it better to breathe through the nose than the mouth?
Breathing through the mouth becomes necessary to prevent nasal congestion.
Because it´s better for our circulatory system.
Nose warms, humidifies, and cleanses/filters air to prepare it for delivery to the lungs.
Nose warms, humidifies, and cleanses/filters carbon dioxide to prepare it for delivery to the environment.
What factors affect the rate at which particles diffuse? Select all that apply.
The size of the particles
The mass of the particles
Time
Temperature.
Container
Select the molecules that are produced in the respiratory process. Select all that apply.
ATP
Glucose
CO2
Oxygen
Water
Some people smoke nicotine free cigarettes. Discuss whether or not this is a good idea.
Emile did an experiment to compare the rate of respiration in woodlice (small crustaceans) and maggots (the larvae of houseflies).
The diagram shows how he set up his experiment. Limewater is a clear liquid. It goes cloudy when carbon dioxide is present.
Describe three variables that Emile needed to keep the same in his experiment.
Emile did an experiment to compare the rate of respiration in woodlice (small crustaceans) and maggots (the larvae of houseflies).
The diagram shows how he set up his experiment. Limewater is a clear liquid. It goes cloudy when carbon dioxide is present.
Emile timed how long it took for the limewater to go cloudy in each tube.
These are his results.
Tube A: 6 minutes
Tube B: 6 ½ minutes
Tube C: 8 ½ minutes
Tube D: 9 minutes
Write a conclusion that Emile can make from his results.
Air enters the body and is warmed as it travels through the (a) .
Air passes through the pharynx and then enters the (a)
The trachea divides into two bronchi. One bronchus enters each (a) .
Each bronchus branches out into smaller tubes called (a) . Air travels through these structures.
At the end of the bronchioles, the air enters one of the many millions of __________ where ______ exchange takes place.
(a)
