Mercury is used in thermometers. Mercury is the freezing point of -40 deg c.

Human body temperature is measured with a Fahrenheit thermometer. The normal human body temperature - 98.4 degrees Fahrenheit.
= -40 Degrees Celsius and Fahrenheit temperature equal to the temperature at
The thermometer used alcohol in the thermometer.

Fahrenheit Celsius / Fahrenheit to Celsius - to change the formula = c / 5 = f-32/9

Eg - human body temperature is 98.4 degrees Celsius in Fahrenheit how much - c / 5 = 98.4-32 / 9 => c / 5 = 66.4 / 9 => 9c = 66.4 * 5 => c = 332/9 = 36.88

Decreases the volume of water - 0 deg c to 4 ° c [4 degree centigrade increase in the volume.]

Highest density of water - 4 deg c
