It seems from your questions that you are surprised how water boils exactly at 100 degree centigrade?. Actually it is otherway round. Scientists D. Data inadequate. Also, as we decrease pressure boiling point of water decreases and at high altitudes, pressure is low so boiling point of water decreases. 0. This also is true because water has very strong hydrogen bonds, which make the boiling point for water a lot higher. This is what happens when you climb a mountain. The core of the Sun extends from the center to about 2025% of the solar radius. False.
Can water be heated to 1000 degrees? are usually physical changes in that no new substances are formed, though the volume occupied by a given number of particles may vary markedly. The strength of these will vary depending on the size of the molecules CO is an unusual molecule P2br4 Compound P2br4 Compound for dierent systems like water complex [12, 13], dichlorine monoxide-hydroxyl radical system [14], tetrahydrofuran-water complex [15, 16], and methanol-water complex [17] Great question! From 1744 until 1954, 0 C was defined as the freezing point of water and 100 C was defined as the boiling point of water, both at a pressure of one standard atmosphere with mercury being the working material. As the water generally boils at 100 degrees Celsius, hence we will use the present tense to fill in the blank. boiling. Was this answer helpful? We can't say that 'Water boils at 100-degree Celcius' is a universal or general truth because it's not that everywhere happens. Isopropanol (rubbing alcohol) boils at 82.3 degrees Celsius. Open in App. It is FALSE that water always boils at 100 degrees Celsius because the temperature at which the water boils depends upon the surrounding pressure. A statement that is always true. For pure water, the boiling point is 100 degrees Celsius (212 Fahrenheit) at one atmosphere of pressure, and the melting point is 0 degrees Celsius (32 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). At standard atmospheric pressure (1 atmosphere = 0.101325 MPa), water boils at approximately 100 degrees Celsius. Why does water not boil at 100 degrees Celsius when it is under greater than normal atmospheric pressure?

1. and coolant will protect the water passages from rust and corrosion, under 170 degrees the engine runs in open loop where there is a richer A/F ratio=mpg drop, so you don't want it running to cool the stock 192 is perfect i run about 200-210 with a 195 thermostat Flame temperature is not as simple as it sounds The coolant
Liquids boil when the pressure of the atmosphere is equal to pressure of the liquid. True or false: the boiling point of water is 100 degrees celsius. This is where it gets interesting. From 1744 until 1954, 0 C was defined as the freezing point of water and 100 C was defined as the boiling point of water, both at a pressure of one standard atmosphere with mercury being the working material. 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.
It is FALSE that water always boils at 100 degrees Celsius because the temperature at which the water boils depends upon the surrounding pressure.
