They all do, but O2 is the most significant.
helium is a gas. air is a bunch of different gasses.
the cold air can change the carbon dioxide gas to a solid
When light passes from air into a gas, its speed and direction may change depending on the properties of the gas. This change in speed and direction is known as refraction. Additionally, some of the light may be reflected back at the boundary between the air and gas, causing part of the light to bounce off.
Most importantly they are of different states of matter. Air is a gas. Brass is a solid.
You can't change volume of a liquid. But only gas it's easy to change
Because the air is coming inside the balloon.
Respiration and photosynthesis.
A liquid can change to a gas, by heating up and evaporating into the air.
Please note that a "change of state" involves TWO states, not just one. Using just the three most common states of matter: * A solid can change to a gas * A liquid can change to a gas * A gas can change to a liquid * A gas can change to a solid * A solid can change to a liquid * A liquid can change to a solid The first four changes in the list above involve gases.
The phase change that occurs when air freshener is sprayed is from liquid to gas. The air freshener is in liquid form inside the container, but when it is sprayed, it is released into the air as a gas or aerosol.
change air filter if that doesn't work change gas filter
I usually change my air filter once a year, that is a good rule of thumb. If you dont change your air filter it can hurt your gas mileage. Its cheap to.
