the freezing point of water is depressed when mixed with ethylene glycol. ethylene glycol is used as a de-icing fluid for windshields and aircraft, as an antifreeze in automobile engines. a mixture of 60% ethylene glycol and 40% water freezes at −45 ∘c.

Respuesta :

The temperature in degrees Fahrenheit is -49°F and the temperature in Kelvin is 228K.

How does temperature conversion take place?

Celsius to Fahrenheit-

In order to convert temperature in degrees Celsius to Fahrenheit, the formula we use is  multiplied by 1.8 (or 9/5) and added to 32.

i.e,  (°C × 9/5) + 32 = °F

Given the water freezes at -45°C, so temperature in degree Fahrenheit is

                    (-45°C × 9/5) + 32 = -49°F

Celsius to Kelvin-

In order to convert the degrees Celsius to Kelvin, the formula we use  is

Kelvin = Celsius + 273.15.

i.e, K = °C + 273.15

Given the water freezes at -45°C, so temperature in Kelvin is

                         K = -45 + 273.15 = 228 K

So after conversion the temperature in degrees Fahrenheit is -49°F and the temperature in Kelvin is 228 K.
