Because alcohol freezes at a lower temperature than water.
Adding salt (sodium chloride) the freezing point of water decrease; for an experiment add gradually salt (in known quantities) and measure the freezing point after each addition.
Although a thermometer CAN be used its presence affects the temperature.
Adding salt to water the freezing point decrease.
It is the freezing point of water and equivalent to 32 degrees fahrenheit it is freezing! In Fahrenheit, it is 32 degrees. It is also the freezing point of water in Celsius.
The melting point and freezing point of water are physical properties.
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
Salt decreases the freezing point of water and increases the boiling point of water.
The freezing point of water occurs at 273.15 K (at StP)
Because water evapurates
0 and 100 0 and 100
freezing point means the point water(H20) freezes at.
Water VAPOUR literally does not have a chemical freezing point because it is in the process of evaporation which is above freezing.
