Which will exert more pressure river water or same amount of sea water?
Sea water will exert more pressure than river water due to its higher density. The pressure exerted by a fluid is directly proportional to its density, so sea water, being more dense than river water, will exert a greater pressure.
What are the two factors that determine the pressure a fluid exerts?
The two factors that determine the pressure a fluid exerts are the depth of the fluid and the density of the fluid. Pressure increases with depth as the weight of the fluid above creates more pressure. Additionally, denser fluids will exert more pressure compared to less dense fluids at the same depth.
Is an ice cube more dense or less dense than liquid water?
Less dense. For most substances, the solid form is more dense than the liquid form; water is a notable exception.Less dense.

How do depth and temperature affect pressure?
As depth increases, pressure also increases due to the weight of the water column above. Temperature affects pressure by influencing the density of a fluid; warm water is less dense and exerts less pressure than cold water at the same depth.
Which is less dense cold air or cold water?
cold air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.
Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
Is cold air heavier than warm air?
False because warm air rises. The particles in cold air are moving more slowly and make cold air more dense than warm air.
Is hot water pressure and cold water pressure equal in pressure?
Pressure is the same whether hot or cold.
Is warm air dense?
No, warm air is less dense than cold air because the molecules in warm air have more energy and are spread out more, resulting in lower density.
What is more dense one mL of water or fifty mL of water .?
If the conditions are the same [temperature, pressure, presence or absence of dissolved substances,...] then they have the same density.
Why is atmospheric pressure generally lower beneath a mass of warm air than beneath a mass of cold air?
Warm air is less dense than cold air. Heat is energy, so the warm air molecules are more energetic and move about more, increasing the distance between molecules - thus less dense. Density is not weight as some have implied. Density is Mass/Volume. Atmospheric pressure =(density)(accel due to gravity)(height of atmosphere) The last two terms are constant regardless of temperature of air. Warmer air has less density and thus the pressure due to this air is less. Alternatively, you could picture two columns of air from the ground to the top of the atmosphere having the same volume. If one has cold air and the other warm, the cold air column, being more dense, will have more mass of air within it since the volume is constant. The greater mass will weigh more due to gravity.

Why do balloons deflate in cold weather?
Because the pressure of a gas is dependent on the temperature. The same amount of gas - as what you have inside your balloon - will have a higher pressure when it's warm, and a lower pressure when it's cold. And higher pressure = more inflation. Lower pressure = less inflation.
Why does cold water in a tube sink to the bottom of room temperature water?
Cold water is dense and cold water sinks, just like air, cold air falls and hot air rises.
How much does air weigh when weighed in air?
Yes, it does. The air has air pressure all around you, about the weight of 2 elephants. Then you would ask, Why are we not we crushed? It is because You breathe in that air and you have the same air inside you that is outside.Yes.Air does have a weight, yes.
Is cold air thicker or thinner than warm air?
Hot air hasLess atmospheric pressure, in other words the air is thinner. ... Cold air is heavier than hot air *at the same pressure*
