Water boils at a temperature greater than 100 oC if the pressure is higher than atmospheric pressure but this has no effect on melting point.
Pipes should be maintained at a temperature above 32 degrees Fahrenheit to prevent them from freezing.
== == Pressure has an effect on the freezing point of water, though it isn't as substantial as the effect of pressure on boiling point. We could say that these values are at standard pressure, but realistically there is no noticeable difference of water's freezing point on various altitudes on earth. But it should be noted that if there are ions dissolved in the water, the freezing point will drop significantly due to the added solute. The melting point of water is the same as the freezing point of water; 32 degrees Fahrenheit or 0 degrees Celsius.
The boiling point of nickel sulfate is approximately 840 degrees Celsius (1544 degrees Fahrenheit).
Yes, because 30 degrees is below freezing.
To prevent pipes from freezing, maintain a temperature of at least 55 degrees Fahrenheit in your home.
You should worry about pipes freezing when temperatures drop below 32 degrees Fahrenheit, especially if the pipes are not insulated or exposed to cold air.
In physics, "boiling" and "freezing" points generally refer to the temperatre and pressure at which liquid water becomes a gas (the "boiling point"), or when liquid water becomes a soild (the "freezing" point). This can be extended to other compounds as well, although the terms "boiling" and "freezing" are not necessarily used. More correctly, we should describe phase transition points, the temperature and pressure where any compound undergoes a change from one state of matter (eg, solid --> liquid, or liquid --> gas, or gas --> plasma).
When it is 0 degrees outside, it means that the temperature is at the freezing point of water. This indicates that it is quite cold and you should dress warmly to stay comfortable and safe in those conditions.
In order to be calibrated, a stem thermometer must have a known reference point, typically the freezing and boiling points of water. It should be immersed in ice water for the freezing point calibration and in boiling water for the boiling point calibration, ensuring the thermometer reads 0°C (32°F) and 100°C (212°F) respectively at those points. Calibration can also be confirmed using a calibration standard or reference thermometer for greater accuracy. Regular checks are necessary to maintain accuracy over time.
The freezing point of other liquids varies depending on the specific substance. For example, the freezing point of water is 0 degrees Celsius, while the freezing point of ethanol is -114 degrees Celsius. Different liquids have different freezing points due to variations in their molecular structure and intermolecular forces.
When the temperature is 47 degrees, NOTHING is in danger of freezing !
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.
