Because alcohol freezes at a lower temperature than water.
Although a thermometer CAN be used its presence affects the temperature.
The freezing point of water in Celsius is 0 degrees.
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.
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.
Water activity takes into account only the available water molecules that contribute to colligative properties, which affects freezing point depression and boiling point elevation more accurately than traditional concentration measurements. It focuses on the water molecules that are free to participate in these colligative properties, providing a more precise measure of the effect on the freezing or boiling point.
The melting point and freezing point of water are physical properties. The melting point is the temperature at which ice (solid) changes to water (liquid), while the freezing point is the temperature at which water (liquid) changes to ice (solid).
Salt decreases the freezing point of water and increases the boiling point of water.
Because water evapurates
Freezing point: 273.15 K Melting point: 373 K
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.
0 centigrade is freezing point of water. 100 c is the boiling point of water, by defination.
