Yes, most water boils at 100 celsius.
Yes, usually water will melt at anything above 0 degrees celsius or boil at 100 degrees. However pressure and altitude can change the required temperature needed for boiling/melting. The higher pressure the lower temperature required and vice versa The higher altitude the less temperature needed
there is less atmospheric pressure than at sea level
yes
The freezing point of water, as defined at a standard temperature and pressure (STP) is 0.0 degrees C and the boiling point is 100.0 degrees C. So it could be said that the difference is 100.0 degrees.
Because for water to turn into snow it needs to cool down to 0 degrees celsius or less. If snow becomes warmer it will no longer be snow.
Water can boil below 100 degrees Celsius depending on the area of the world. A lab was conducted in science class that our water boiled at 94.6 degrees Celsius. The average boiling point for water is 100 degrees Celsius but that does not mean it will always be that degree to boil.
On top of a mountain
No. Pure water boils at 100 degrees Celsius or less.
The temperature of boiling water is 212 degrees Fahrenheit. This is 100 degrees Celsius. Water will freeze at 32 degrees Fahrenheit (0 degrees Celsius).
For every 1000ft up you go water boils 1 degrees less, so Kilimanjaro is 19340 feet high so water will boil at approximately 80.7 degrees Celsius.
At Zero degree Celsius.(or less)
Yes, usually water will melt at anything above 0 degrees celsius or boil at 100 degrees. However pressure and altitude can change the required temperature needed for boiling/melting. The higher pressure the lower temperature required and vice versa The higher altitude the less temperature needed
When the pressure is reduced. Water only boils at 100 degrees Celsius when the air pressure is one atmosphere. So up a mountain, where the air pressure is lowered, water boils at a lower temperature.
As the water absorbs heat, at the temperature of 100 degrees Celsius or 212 degrees Fahrenheit, the liquid water boils and becomes a gas. The gaseous water, called "steam", expands and becomes far less dense. The steam bubbles rise to the surface.
It is: -4 degrees Celsius
Water at -20 degrees Celsius; heat will expand matter, so at +40 degrees Celsius, water would have less density. * * * * * That would be true if there were no phase change. Unfortunately for the above answer, water freezes at 0 deg C and that phase change is accompanied by an expansion. As a result, water at 40 deg C is denser that water (ice) at -20 deg C.
264.15 degrees Kelvin is 15 degrees Celsius less than 6 degrees Celsius.
