How do you separate sulfur from mixture of carbon particles and powdered roll sulfur?
One way to separate sulfur from a mixture of carbon particles and powdered roll sulfur is by using a process called sublimation. Sulfur sublimes at a lower temperature than carbon, so when the mixture is heated, the sulfur will turn into a gas and can be collected separately from the carbon particles.
Describe what happens to the particles in substances when the substances is heated?
electrons spontaneously "jump" from a lower orbital to a higher one
Why are whiskies distilled?
All alcohol is distilled, it is the process in which it is made. The ingredients are put into a pot or column still and heated, turning the liquid into vapour, alcohol has a lower boiling point, as the liquid is heated the alcohol turns into a vapor and is separated from the water. The more you distill the alcohol the purer the product you get.
What happens to the density of a heated iron block?
The density will decrease because the heated metal contracts and its particles slow down.
What happens to its density when a gas is heated?
When a gas is heated, its density decreases because the particles move faster and spread out, increasing the space between them. This results in a decrease in the number of gas particles per unit volume, leading to a lower density.
What is the temperature of water vapour?
It starts from 100 celcius in 1atm and can be risen further. At lower pressures eg on tops of mountains, it can be lower. Water boils when the pressure of water vapour exceeds the external atmospheric pressure. Below that, any bubble of water vapour which might start to form is immediately compressed back to liquid.
What happens to oxygen in the water when it is heated?
When water is heated, it loses its ability to hold dissolved oxygen. This means that as the water temperature increases, the amount of oxygen available for aquatic organisms decreases. This can lead to lower oxygen levels in the water, which can be harmful to aquatic life.
Would A decline in sulfur dioxide has led to a lower pH in precipitation?
Yes, a decline in sulfur dioxide emissions can lead to a lower pH in precipitation. Sulfur dioxide can react with water in the atmosphere to form sulfuric acid, which contributes to acid rain. A decrease in sulfur dioxide emissions reduces the amount of sulfuric acid formed, resulting in lower pH levels in precipitation.
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
Why heated gas become lighter?
because..................................................................................................................... density of heated gas is lower than cooled gas.
What happens when glucose is heated at 120 degree celsius?
The products depend upon the pressure. At high pressure HMF alongwith levulinic acid will form. At lower pressure some aromatics could form.
By what process is air moving to a lower altitude heated?
Adiabatic heating
