Some facts#
- Cooling mixtures are mixtures of substances forming solutions with a low solidification temperature.
- Such mixtures may be, for example:
- a mixture of ice and cooking salt (NaCl) in a weight ratio of 3: 1, allows to reach the temperature of -21.1 °C,
- a mixture of ethyl alcohol and so-called dry ice (CO2 in the solid state), allows you to reach temperatures down to -68 °C,
- a mixture of ice and calcium chloride hexahydrate (CaCl·6H2O) in a weight ratio of 100: 43, allows to reach a temperature of -55 °C,
- etc.
- a mixture of ice and cooking salt (NaCl) in a weight ratio of 3: 1, allows to reach the temperature of -21.1 °C,
- An example of using a cooling mixture in everyday life is sprinkling the roads with salt in the winter. Salt water has lower solidification temperature than pure water without admixtures. Thanks to this, despite the negative temperatures (i.e., those at which the water would freeze) we avoid icing of the road surface.
- One of the most effective known cooling substances is liquid nitrogen . It is not a mixture, but often for practical reasons it is listed alongside coolant mixtures. When using liquid nitrogen, a temperature of -190 °C can be achieved.
