Hello, my name is Walter Unglaub and this is freezing point of dichloromethane. So, dichloromethane is an organic compound that has the chemical formula CH2CL2, meaning there's a carbon atom, two hydrogen atoms, and two chlorine atoms in the molecule. And its freezing point is actually the same of course as its melting point, and that temperature in degrees Celsius, T freezing, is equal to negative 96.7 degree Celsius approximately. If we wanted to re-express this temperature in units of kelvin, then we would have to use the formula kelvin is equal to Celsius plus 273.15. So, when we stick in this temperature into this equation, we get out T freezing in units of kelvin is equal to 176.45 kelvin. Finally, if we wanted to re-express this freezing point temperature in units of degrees Fahrenheit, we would use the conversion formula degree Fahrenheit is equal to nine-fifths times the degrees in Celsius plus 32. So, when we plug in this number into this equation, we have in Fahrenheit the freezing temperature is approximately equal to negative 142.06 degrees Fahrenheit. So, these three are equivalent, and they represent the temperature at which dichloromethane freezes, or alternatively melts if you're increasing the temperature. My name is Walter Unglaub, and this is freezing point of dichloromethane.
