Is pure ammonia soluble in hot or cold water?
Ammonia is soluble in both hot and cold water, with a higher solubility in cold water.
Are the cold gases more dense than the hot gases and which are they?
Cold gases are typically denser than hot gases. This is because the molecules in cold gases move more slowly, allowing them to be packed more closely together, leading to higher density. Heating a gas causes the molecules to move faster and spread out, resulting in lower density.
How are temperature and density of air related?
As temperature increases, the density of air decreases. This is because the air molecules become more energetic and spread out, leading to lower density. Conversely, as temperature decreases, air density increases due to the molecules losing energy and moving closer together.
What gets cold first hot or cold water?
Isn't cold water already cold? I would say cold water gets cold first. I've heard that hot water freezes faster than cold water.
Which is what happens when we put a cup of hot water with dye on a glass of cold water?
When you put a cup of hot water with dye on a glass of cold water, the hot water will rise to the surface of the cold water due to differences in temperature and density. This creates a mixing or diffusion effect, causing the dye to spread and color the cold water as the two temperatures equalize.
What has a higher density cold or hot water?
Cold water has a higher density than hot water. As water cools, its molecules come closer together, increasing its density. Conversely, hot water molecules are more spread out, resulting in lower density.
How density and temperature of air related?
cold air has higher density, by hot air is opposite
Density of galvanized iron?
A galvanized iron is similar to steel; it is material that composed of cold-rolled and hot-dip galvanized mild steel. It has 7850 kilograms per cubic meter density same as a steel.
Why does cold air have a higher density than warm air?
Cold air is denser than warm air because the molecules in cold air are closer together, leading to a higher mass per unit volume. When air is heated, the molecules gain kinetic energy and move farther apart, resulting in lower density.
What is the density of hot steel?
density changers with heatyou need a set heat
What is the density of cold air?
The density of cold air is higher compared to warm air. This is because cold air molecules are closer together, making it denser. Generally, the density of cold air is around 1.275 kg/m³ at 0°C.
Does hot air have high density or low density why?
Hot air has low density because its molecules are more spread out and have higher kinetic energy, causing them to move further apart. This leads to a decrease in the air's mass per unit volume, resulting in lower density compared to cold air.
What is density of hot die steel?
100*100*55*6.85
Is 65 c hot or cold?
It is hot, higher temperature is hot and lower is cold. Cold temperature is from 0c to about 10c.
Is cold rolled harder than hot rolled steel?
They are two different things. Zinc plated means it's coated in zinc. Cold rolled means it's "smashed" into shape without added heat. So you could have something that's cold rolled AND zinc plated!
What temperature does a basketball bounce higher in hot or cold?
Hot
What must be done to hot-rolled steel in the mill before it can be cold finished?
Hot rolled steel must be descaled by pickling in acid with a lime water rinsebefore it can be cold finished
