Is helium dense or less dense than water?
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
How does temperature affect the atmospheric pressure of a place?
when temperature of air increases it becomes less dense and expands rising up which causes the pressure to drop
What is the most dense temperature of air?
The most dense temperature of air occurs at lower temperatures, specifically around -60 degrees Celsius (-76 degrees Fahrenheit), at which point air density reaches its maximum. At this temperature, the molecules are closely packed together, resulting in higher density compared to warmer temperatures. However, real atmospheric conditions also play a role, with humidity and pressure influencing air density in various environments.
Stars can form most easily in clouds that are?
Cold, dense, and massive. These conditions allow gravity to overcome internal pressure and initiate the process of nuclear fusion, leading to the formation of a star.
When dense air sinks toward earths surface what is it called?
The dense air sinking towards the Earth's surface is called subsidence. Subsidence can lead to high pressure systems and stable weather conditions.

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.
How does air pressure vary with temperature changes?
Air pressure decreases as temperature increases, and air pressure increases as temperature decreases. This is because warmer air is less dense and exerts less pressure, while cooler air is denser and exerts more pressure.
Does dense air move from hot air to cool air?
Yes, in general, dense air will move from hot air to cool air due to differences in temperature and pressure. This movement of air helps to balance out the temperature and pressure gradients between the two regions.
How does temperature affect the atmospheric pressure of a place?
when temperature of air increases it becomes less dense and expands rising up which causes the pressure to drop
Is old gas less dense than new gas?
Not if they are both at the same temperature and pressure.
Are temperature and pressure directly proportianal?
Yes, temperature is directly proportional to pressure. As pressure increases, temperature increases, hence the extremely high temperature at the earth's core. Actually, when air cools, its molecules huddle closer together. The air becomes more dense (higher pressure) and it sinks. temperature goes down=pressure goes up
Is ammonia more dense or less dense than air?
Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
What does temperature have to do with air pressure?
Temperature affects air pressure because as air warms up, it expands and becomes less dense, causing it to rise. This leads to lower air pressure at the surface. Conversely, as air cools, it contracts and becomes more dense, causing it to sink and creating higher air pressure at the surface.
Why is hydrogen less dense than water?
At standard temperature and pressure (STP) hydrogen is a gas and water is a liquid.
Does air pressure and temperature change with altitude?
Yes, air pressure decreases with altitude because the atmosphere becomes less dense. In contrast, temperature changes can vary with altitude; typically, temperature decreases with altitude, but there are atmospheric layers where temperature may increase, known as inversions.
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.
