Explain why a brick and a feather fall in different speed?
A brick falls faster than a feather due to differences in mass and air resistance. The brick has more mass, so gravity exerts a greater force on it, causing it to accelerate faster. Additionally, the feather experiences more air resistance due to its larger surface area, slowing its descent.
Why humid air is lighter than dry air?
Humid air is lighter than dry air because water molecules in humid air have a lower molecular weight compared to the nitrogen and oxygen molecules that make up dry air. This lower molecular weight causes humid air to have a lower density, resulting in it being lighter.
Why is water denser than air?
Water is denser than air because water molecules are closer together and have a higher mass per unit volume compared to air molecules. This is due to the intermolecular forces present in water that cause molecules to be more tightly packed. Air molecules are further apart and have lower mass, resulting in air being less dense than water.
Sentence using the word air mass?
The cold air mass that moved in from the north brought lower temperatures and strong winds to the region.
Air is less dense than water because?
Air is less dense because the particles are mainly of lower molecular mass with similar volume, thus having an inherently lower density, and also because air is free to expand (as it is a gas) where water is liquid and so cannot expand or contract to any major degree.
A feather falls through the air more slowly than a brick because of?
If you dropped them in a vacuum, they would fall at the same rate. However, when you do it in air, the friction from the air will slow the feather considerably, as the surface area to mass is much greater then that of the brick.
How an air balloon flies in the air?
The hellium inside baloon has lower mass than oxygen, nitrogen cocktail.
Explain why a brick and a feather fall in different speed?
A brick falls faster than a feather due to differences in mass and air resistance. The brick has more mass, so gravity exerts a greater force on it, causing it to accelerate faster. Additionally, the feather experiences more air resistance due to its larger surface area, slowing its descent.
Why is a brick more dense then a sponge?
A brick is more dense than a sponge because it has more mass packed into a smaller volume. Bricks are made of solid materials like clay or concrete, which have tightly packed molecules, while sponges are porous and contain a lot of air or water pockets, leading to lower density.
Does warm air have any mass?
All air has mass. Warm air of the same volume as cold air will have a lower mass.
Which has the lowest mass air or clay?
That question doesn't mean anything, mass is mass. If you are asking which has a greater mass per unit volume, also known as density, then the air will have a lower density than clay.
Is air more dense than oil?
No, oil is more dense than air. The density of a substance is determined by its mass and volume, and oil has a greater mass per unit volume compared to air.
Cold air mass?
A cold air mass is a large body of air with lower temperatures than the surrounding air. As it moves into an area, it brings cooler temperatures, often leading to a decrease in humidity and the potential for precipitation. Cold air masses can result in significant weather changes, such as cold snaps, snowfall, or frost.
Why does a feather fall through the air more slowly than a brick?
It is slowed down by air resistance.because feather's weight is negligible as compare to force of gravityA feather will fall through the air more slowly than a brick because it is lighter than a brick and it's small fur on it will slow it down
How do you increase the relative humidity of an air mass?
Add water (vapor) ... evaporation. Lower the temperature of the air mass.
Which has the lowest mass bricks having a density of 2000 kg per meter cubed or air having a density of 1 kg per meter cubed?
Air definitely has lower mass than bricks.
Why do hot air balloons fly?
The Helium inside of the balloon has a lower atomic mass than the Nitrogen and Oxygen cocktail outside of it.
