-15 degrees
The temperature is 0 degrees Celsius.
The Celsius freezing temperature is 0 degrees Celsius. At this temperature, water freezes and turns into ice.
Both Kelvin and Rankine are absolute temperature scales (The bottom of the scale is absolute 0 meaning there is no lower temperature). Rankine is used more by engineers and Kelvin by scientists
The temperature range is from -50 to 0 degrees, where -50 degrees is the lower limit and 0 degrees is the upper limit. The temperature is in the negatives and ranges from extremely cold to freezing.
Yes, it is impossible to have a temperature below 0 Kelvin. Absolute zero at 0 K is the lowest possible temperature where particles have minimal thermal motion. Any temperature below 0 K would imply that particles have negative thermal energy, which is not physically meaningful.

For the evaporation - at any temperature over 0 deg. C; of course, increasing the temperature and the exposed area of the container (tank) evaporation will be faster.
- Separation by distillation: at 100 deg. C - Separation by evaporation: at any temperature above 0 deg. C.
No, evaporation will take place at any temperature between 0 and 100 deg C.
The only gauge that measures pressure above 0 psig is called a pressure gauge or more specifically, a gauge pressure gauge. This type of gauge measures pressure relative to atmospheric pressure, indicating values greater than atmospheric pressure (0 psig). It is commonly used in various applications, such as in industrial processes and HVAC systems.
No, 0 psig (pounds per square inch gauge) and 14.7 psia (pounds per square inch absolute) are not 14.7 pounds apart; they represent different reference points. Psig measures pressure relative to atmospheric pressure, while psia measures it relative to a perfect vacuum. Since 0 psig means the pressure is equal to atmospheric pressure, it corresponds to 14.7 psia at sea level. Therefore, they are actually the same pressure level.
Evaporation will not stop completely at any temperature, as it is a process driven by energy in the form of heat. However, at very low temperatures, the rate of evaporation will be significantly slower compared to higher temperatures because less energy is available to overcome the intermolecular forces holding the liquid molecules together.
For the evaporation - at any temperature over 0 deg. C; of course, increasing the temperature and the exposed area of the container (tank) evaporation will be faster.Water will evaporate at any temperature over its melting point. Either evaporating in a flattened tank or introducing a heating source will enhance the process. Heat until there is no water remaining to extract the salt.
0 mmHg is equivalent to 0 psia because both represent a pressure of zero relative to absolute vacuum. However, 760 mmHg is equal to 14.7 psia, not 0 psig. 760 mmHg is equivalent to atmospheric pressure, which is the reference point for psig.
Yes, evaporation can occur at temperatures below 0°C, as the process is based on molecules escaping from the liquid surface to the gas phase. However, at lower temperatures, the rate of evaporation is slower due to reduced kinetic energy of the molecules.
