Why does steam of 100 degree c cause more severe burns than boiling water at 100 degree c?
Because steam includes the latent heat of vapourisation. As a result, the energy in a kilogram of steam at 100 deg C is 2257 kJoules more than that in a kilogram of water at 100 deg C.
Can a 20 g of steam cause more of a serious burn 20 g of liquid water?
Yes. Each gram of steam at 100 deg C contains the latent heat of vaporisation more than a gram of water at 100 deg C. This is equal to approx 2.26 kiloJoules per gram.
How many decibels is a shotgun?
It depends really how close that shot explodes to you ear. The more far away the better. Avoid soundpressure levels of more than 120 dB. That hurts.
Is hot water more buoyant than cold water?
yes
Why do certain planes emit visible gaseous trails in the sky while others do not?
It has more to do with the air conditions than the planes. All planes give off exhaust from their engines. This contains carbon dioxide and monoxide, some nitrogen oxides and lots of water. The water is emitted as a gas (steam) that under the right cold and humidity conditions condenses into tiny water droplets and these very quickly freeze into very fine ice. These conditions are found more commonly in the upper atmosphere, so high flying planes tend to leave contrails (condensation trails) Low flying planes emit the same exhaust, but in the warmer air at lower altitudes the water content does not turn to water and ice droplets - it remains as an invisible gas.
What is the meaning of scald?
To burn with hot liquid or steam; to pain or injure by contact with, or immersion in, any hot fluid; as, to scald the hand., To expose to a boiling or violent heat over a fire, or in hot water or other liquor; as, to scald milk or meat., A burn, or injury to the skin or flesh, by some hot liquid, or by steam., Affected with the scab; scabby., Scurvy; paltry; as, scald rhymers., Scurf on the head. See Scall., One of the ancient Scandinavian poets and historiographers; a reciter and singer of heroic poems, eulogies, etc., among the Norsemen; more rarely, a bard of any of the ancient Teutonic tribes.
Why does water take up more space as steam then it does as liquid water?
Sort of, as steam water spreads around more so you could say that water takes up more space as steam.
Do steam heating systems use more water than hot water systems?
no because its not the water your using its the steam from the water
Why does steam have a greater volume than that of water?
Steam has a greater volume than water because the water molecules in steam have more energy and move more quickly, causing them to spread out more. As steam is in the gaseous phase, the molecules are further apart compared to the liquid phase of water, which results in a greater volume.
Why steam takes up more space than liquid water?
why does steam take up more space than liquid water
Why steam is more dangerous than boiling water?
steam scalds are more serious than boiling water scalds because steam when condenses onto the more cooler skin, it loses latent heat of vaporization (to become water at 100 degrees Celsius) also it loses thermal capacity to become equal to the temperature of the skin (37 degrees Celsius). boiling water loses only thermal capacity as it cools down to 37 degrees Celsius from 100 degree Celsius.
What causes a more severe burn - water or steam?
Steam is more dangerous because the temperature is higher.
Why is a steam burn worse then a water burn?
A steam burn is generally more severe than a water burn because steam carries more heat energy than water due to its high temperature. Steam can cause more damage to the skin upon contact and penetrate deeper into the tissue, resulting in a more serious burn.
What cause more burns steam or boiling water?
Steam can cause more severe burns than boiling water because steam has a higher heat energy content. When steam comes into contact with the skin, it releases this heat energy, causing more damage than boiling water at the same temperature.
What is the difference between water and steam?
Water is the liquid form of H2O, while steam is the gaseous form of water when it reaches its boiling point. Steam has higher energy and occupies more volume compared to water.
Why does steam take up more space than liquid water?
Steam takes up more space than liquid water because the molecules of water in steam have higher energy and are further apart from each other compared to when they are in liquid form. This causes steam to have a larger volume and be less dense than liquid water.
What is the name of water that is a gas?
Steam. Not to be confused with vapor, which is a suspension of liquid water molecules in another gas.
