Question

glycerol is heated from 0 degree Celsius to 50 degree Celsius then the temperature it is 17.8 degree Celsius the temperature remains constant for while and only after sometime it starts to increase again why​

Answer 1

When glycerol is heated from 0°C to 50°C, its temperature remains constant for a while at 17.8°C an then again starts increasing because 17.8°C is the melting point of glycerol.

• Melting point of a solid is the temperature at which it gets converted into liquid if heat is supplied to it.
• Glycerol is a solid below 17.8°C and is a liquid when the temperature is above 17.8°C.
• When glycerol is heated its temperature increases upto 17.8°C and then all the heat supplied is used to convert solid glycerol into liquid glycerol, which causes the temperature to be constant for a while at 17.8°C.

Answer 2

Answer:

bcoz the boiling point of glycerol is 17.8℃
