Answer:
Q1 ice water and salt
dry ice and alcohol
Explanation:
it is a mixtureof two or more substances.which can be used to produce temperature below the freezing point of water .it is mixture generally used to achieve temperature less than 0degree celcius .i.e below the freezing point of water
Answer:
hey
Explanation:
1 Water, ice, snow, and various salts and acids will form freezing mixtures that attain a temperature of — 50°C. Salts in dilute acid solutions lower temperatures more than salts in a water solution.
2The triple point of carbon dioxide is at 75.1 psi, or 5.11 atmospheres of pressure, and -56.6 degrees Celsius. So at pressures of greater than 75.1 psi, carbon dioxide will liquify as it warms. At lower pressures, dry ice does not melt.
