Question

The melting point of substance X is -20 degrees Celsius and the boiling point is 90 degrees Celsius. How many Celsius degrees are there between the melting point and the boiling point?
20 degrees C
70 degrees C
90 degrees C
110 degrees C

Answer 1

Answer:

The answer is 110 degrees C.

Step-by-step explanation:

The melting point of substance X is -20 degrees Celsius and the boiling point is 90 degrees Celsius.

To find the difference between the degrees, we will subtract the values.

So, the difference between these points will be =

$90-(-20)$

= $90+20=110$

The answer is 110 degrees C

Answer 2

To find the distance between 2 numbers you must take the absolute value of the difference

|90-(-20)|
|110|
110

110 degrees celsius
