What is the composition of the liquid?
The composition of liquid air is: 80 % nitrogen, 19 % oxygen 0,9 % argon, 0,1 % minor gases.
What is the difference between a liquid and its chemical composition?
A liquid is a compound or a mixture; the chemical composition is representative for this liquid.
What happens when liquids are exposed to air?
It evaporates :)
Why do liquids smell?
Liquids can smell due to the presence of volatile molecules that are released into the air and are detected by our sense of smell. These molecules can come from the liquid itself or from substances dissolved in the liquid. The smell of a liquid can give us information about its composition and quality.
Why does liquid nitrogen exposed to air is a physical change?
When liquid nitrogen is exposed to air, it rapidly evaporates and turns into nitrogen gas. This process is a physical change because only the physical state of the substance is changed from liquid to gas, without altering its chemical composition.
How does air temperature change with atmospheric composition?
The composition of air depends upon altitude.
How does the composition of air change at the top of amountain?
The composition is the same, the air is just less dense.
Is cooling a mixture of air and kerosene vapor so that liquid kerosene condenses out a physical change?
Yes, cooling a mixture of air and kerosene vapor to condense liquid kerosene is a physical change. This process involves a change in the state of the kerosene from vapor to liquid without altering its chemical composition. The air remains unchanged as well, reinforcing that this transformation is a physical rather than a chemical change.
What is the word for when air is cooled into liquid?
Air to liquid = condensation
What is the composition of gases found in inhaled air?
gas composition in air is the sum of the gas individual element and that of the air i.e oxygen and nitrogen
Is liquefaction of air physical change?
Yes, liquefaction of air is a physical change because it does not involve any change in the chemical composition of the air molecules. It is a reversible process where the air transitions between gas and liquid states due to changes in temperature and pressure.
Milk is liquid curd is semisolid why?
The chemical composition is different.
