When substances change state, or under go a phase change (solid to liquid, or liquid to gas), it takes a transfer of energy.
This can be several times the amount of energy to raise the substance a degree in temperature. This is also the reason why boiling water tends to stay at 100°C until all the water boils away.
So, when boiling water, one must add energy (the heat of vaporization)
When condensing water, one must remove the same amount of energy.
It takes 1 calorie to raise 1 gram of water 1°C.
It takes 539 calories to turn 1 gram of water (at 100 °C) to steam.
So, if 1 gram of steam (what was 1 ml of water) is condensed on your arm, it actually transfers the amount of energy to your arm equivalent to dropping the temperature 539°C, or equivalent to dropping the temperature of over 1/2 liter of water a single degree Celsius.
because when it condenses on your skin, it is very hot air and so it burns your skin
Because of the heat bubble , steam & evaporaion
Y
😍😍😍
Because a big difference of temperature exist.
Bad cuz some girls Get really bad cramps that they can't even get out of bed or walk is really painful. I HATE CRAMPS>=[
Because the smell of the smoke spreads as the gas particles diffuse throughout the area where the sticks are being burned.
Using steam carpet cleaners is perhaps the most accepted technique for cleaning carpets, especially in large spaces such as hotels and offices.

Read on to find out the lots of benefits of steam carpet cleaners. Carpets are hard to maintain.

I feel your pain. How did that feel? Can you feel the love?
Its like touching boiling water (100 degrees)
Your fingernails feel painful and red because your skin is attached to your nails.
painful
they know because they have proved that there are somethings called molicules and they are all scrunched up together and they try to take up as much room as possible! and if they for example when you boil the kettle and all the steam comes out if there are molicules near they will move all about like mad because of the heat and when it is cold they are all together but when they feel the steam the particles separate!
Painful!

The headaches are very painful as they directly hit a part of your head. You feel very bad when you have a headache.
It would feel quite painful - you would get torn apart.

It can be painful for your family members to see you like that but if you meant you, yourself can feel pain then no, but its a very scary situation.
Dialysis in itself is not painful. You may feel tired and washed out after your treatment, but it is not "painful" If you are talking about needles then there is a cream called EMLA that numbs the area. To say it is more painful than renal failure is soooo untrue. Most people feel better and get there strength back. If you don't get the treatment then you die.
