Question

7.
The melting point of hydrogen is -259°C. The melting point of oxygen is-219°C. Whose melting point
is greater and by how much.​

Answer 1

Answer:

The melting point of hydrogen is greater by -40°C.

-259 = 259

-219 = 219

This, we are doing only for the subtraction.

259 - 219 = 40

40 = -40

Answer 2

Melting point of hydrogen is greater

Step-by-step explanation:

Melting point of hydrogen is greater because it is 259⁰c which is greater than melting point of oxygen. i.e. 219⁰c . It is greater by (259-219)⁰c=40⁰c
