Question

Isopropyl alcohol and water look very similar. Water has a melting point of 0°C and a boiling point of 100°C. How could you distinguish sample of these substances using heating curves?

Answer 1

The heating curve of Isopropyl alcohol moves lower than water.

Step-by-step explanation:

Boing point of Isopropyl alcohol is 82.5 °C while boiling of water is 100 °C and melting point of Isopropyl alcohol is -89 °C while melting point of water is 0 °C. Heating curve of Isopropyl alcohol moves lower than water because boing point of Isopropyl alcohol is 82.5 °C which is lower than water i. e. 100 °C so that's why the curve of Isopropyl alcohol moves lower than water.
