- What makes water boil? - Physics Stack Exchange
Using this water boiling point calculator, Boiling point at sea level (1 atm or 29 92 inches of Hg) is approximately 212 °F whereas at a height of about 5000 ft (24 9 inches of Hg), it is 203 °F Share
- At what pressure will water boil at room temperature and why?
What causes water to boil is not only the ambient temperature but rather the pressure acting upon the water surface Example, at sea level where atm Pressure is 14 7 psi, water will start to boil at 212 degrees F However At a higher elevation, say in Denver, Co
- temperature - How does water evaporate if it doesnt boil? - Physics . . .
When you boil water on the stove, you get steam This then cools when it comes into contact with the air, increasing the relative humidity above 100%, so the water vapor condenses into mist If the relative humidity is bigger than 100%, water vapor will condense from the air, becoming dew and or mist
- Water in vacuum (or space) and temperature in space
The specific latent heat of evaporation of water is 2270 kJ kg The specific heat of water is 4 2 kJ kgK Hence, evaporating 1 gram of water can cool 2270 4 2 = 540 grams of water by 1°K, or 5 4 grams by 100°K which is about the difference between room temperature and water (de)sublimation temperature in space
- Why doesnt water boil in the oven? - Physics Stack Exchange
The water didn't evaporate It boiled If you could look closely at the water in the pot in the oven you would see small bubbles rising within the liquid, which would indicate boiling But you wouldn't necessarily observe what is sometimes referred to as a "rolling boil, i e , large bubbles rising in the water indicating a high rate of boiling
- Why does temperature remain constant when water is boiling?
The excess energy is no longer in the liquid which remains at a constant temperature The steam however does not necessarily do the same, depending on the conditions of the other gas around the liquid Also the reason why water boils with bubbles rising up from the bottom is mostly due to uneven energy distribution within the liquid
- Why water inside a vessel placed in a body of boiling water does not boil?
The temperature of the water inside the sac should be the same as that of outside water, i e , 100 deg celsius Similarly if to place a glass tumbler of water inside a pan placed on fire, the water will boil only inside the pan, but not in the tumbler
- Is the boiling point of water really 100°C? If so, how come water . . .
Water in a plate left in the open will evaporate (same as boiling) at say 20⁰ C room temperature as long as the air is not already saturated with water vapor Water will "boil" (evaporate) at 20⁰ C as long as the contribution of the water vapor to the total pressure of the atmosphere (about 1 atm) is small, say < 0 2 atm
