If the liquid is moving, third degree burns (reddened skin) can occur within a few seconds, second degree (blisters) would take a bit longer. Deep tissue damage (first degree burns) would take longer yet, and might not occur at all depending on a number of factors, such as where the heat is applied. In all cases, the location of the heat on the body is a factor. The inside of the upper arm, for example, will suffer damage much faster than the palm of the hand. If you have a water heater with a thermostat, it is a good idea to keep it at about 120 degrees tops. This is hot enough for washing, minimizes the chance of burns, and will save energy. Even with a home diswasher, 120 degrees is hot enough. (Commercial dishwashers require higher temperatures because of the way they function.)
Sure. Boiling point is related to pressure. Increase the pressure and boiling will occur at a higher temperature.
No. The temperature doesn't have to be the same for a liquid to evaperate. so if the temperature was constanly changing then the liquid could still evaperate.
The temperature must be hot to do so.
The minimum temperature is about 10,000,000 degrees Celsius.
In order for snow to occur, the ground temperature must be a temperature of 32 degrees or lower.
At standard pressure, CO2 does not occur as a liquid, the solid phase turns directly into a gas. Liquid carbon dioxide only forms at pressures higher than 5.1 atm. The actual boiling point depends on the pressure. At a particular pressure the liquid may have any temperature between the melting and boiling points. At the lowest pressure where it can exist, liquid carbon dioxide would have a temperature of -56.6 degrees C, or -69.88 degrees F. Under normal pressure conditions, carbon dioxide goes from gas straight to solid when the temperature reaches - 78.5 degrees C.
Evaporation occur at the surface of a liquid and at any temperature under the boiling point.Vaporization occur only at the boiling point and in the entire volume of the liquid.
For water it is 100 degrees celsius, however it is different for other liquids ------------------------- Generally, boiling point is the temperature at which the liquid's vapour pressure is equal to the external atmospheric pressure.
Flash point is the temperature at which a flash will occur across the face of a liquid and go out. Fire point is the temperature at which a flash will occur above the liquid and the resultant fire will continue to burn.
All elements can exist as liquids at some temperature or other. At standard room temperature, only bromine and mercury are liquid. However, gallium has a melting point of only 29.76 degrees C (85.57 degrees F) which is not far above standard room temperature, and can occur naturally in some places.
the temperature has to be 32 degrees or less during precipitation
