Question

The melting point of hydrogen is -259°C. The melting point of oxygen is -219°C. How much more is the melting point of oxygen than the melting point of hydrogen?

a) 40°C
b) 20°C
c) 50°C
d) 60°C

Answer 1

The melting point of oxygen is 40°C higher than the melting point of hydrogen.

Step-by-step explanation:

The melting point of oxygen is -219°C, while the melting point of hydrogen is -259°C. To find the difference between the two, we subtract the melting point of hydrogen from the melting point of oxygen: -219°C - (-259°C). When subtracting a negative number, we can think of it as adding the absolute values: -219°C + 259°C. This gives us a result of 40°C. Therefore, the melting point of oxygen is 40°C higher than the melting point of hydrogen.
