Liquids boil when the pressure of the atmosphere is equal to the pressure of the liquid. Also, as we decrease pressure boiling point of water decreases and at high altitudes, pressure is low so boiling point of water decreases. True B. Can water be heated to 1000 degrees? Water boiling at 100 degrees Celsius or water melting at 0 degrees Celsius both are an example of physical change.

Water in high places will boil at a lower temp where deep it will require a higher temp. Pressure is the key and your 100C is based on sea level t There are two conventions regarding the standard boiling point of water: The normal boiling point is 99.97 C (211.9 F) at a pressure of 1 atm (i.e., 101.325 kPa).

Boiling occurs when the vapor pressure reaches or exceeds the surrounding pressure from the atmosphere or whatever else is in contact with the liqu At standard atmospheric pressure (1 atmosphere = 0.101325 MPa), water boils at approximately 100 degrees Celsius. No, the boiling point of water depends on the air pressure in the surrounding environment, which changes the thermal energy (temperature) required

Mackie in his book Cement of the Universe analysed causation as an INUS condition, meaning an insufficient but non-redundant part of an unnecessary but sufficient condition. And removing dissolved air from water can easily raise its boiling temperature by about 10 degrees centigrade. In space, you can boil water without supplying any heat at all, since theres not enough ambient pressure to keep it in liquid form.

By the way your sentence is a 0 conditional, in case that you are interested. No. That is the boiling temperature at sea level. The temperature varies based on atmospheric pressure because the escaping water vapor must overco

A. Reduce the atmospheric pressure around the water, by using a vacuum pump and a closed container, else go into a very high altitude. The new definition of centigrade is different, it depends on absolute zero degrees and the triple point of water. In the case of your water boiling example, one can heat water to 100 degrees without it boiling because it may become superheated, so it is not sufficient.

Does the temperature water boils at always stay the same?

As the water generally boils at 100 degrees Celsius, hence we will use the present tense to fill in the blank. It is FALSE that water always boils at 100 degrees Celsius because the temperature at which the water boils depends upon the surrounding pressure.

We can't say that 'Water boils at 100-degree Celcius' is a universal or general truth because it's not that everywhere happens.

What is the freezing point of water? The core of the Sun extends from the center to about 2025% of the solar radius. The statement is a universal truth. are usually physical changes in that no new substances are formed, though the volume occupied by a given number of particles may vary markedly. If you heat water to 100C (at standard temperature and pressure) then it boils. So at 101.3 vapor pressure, water will turn to vapor (boil) at 100c. No Comments.
