Answer 1

is that correct t

Answer 2

To find the difference between the boiling points of oxygen and hydrogen, we'll subtract the boiling point of hydrogen from the boiling point of oxygen.

Boiling point of oxygen: -182.9 °C
Boiling point of hydrogen: -252.87 °C

Now, calculate the difference:

\[
\text{Difference} = \text{Boiling point of oxygen} - \text{Boiling point of hydrogen}
\]

\[
\text{Difference} = -182.9 - (-252.87)
\]

This simplifies to:

\[
\text{Difference} = -182.9 + 252.87
\]

Now, perform the addition:

\[
\text{Difference} = 252.87 - 182.9 = 69.97
\]

Thus, the difference between the boiling points of oxygen and hydrogen is:

\[
\boxed{69.97}
\]

Answer 3

Let's double-check the calculation step-by-step for accuracy.

1. The boiling point of oxygen is **-182.9 °C**.
2. The boiling point of hydrogen is **-252.87 °C**.

To find the difference between the boiling points, we need to use the formula:

\[
\text{Difference} = \text{Boiling point of oxygen} - \text{Boiling point of hydrogen}
\]

Substituting in the values:

\[
\text{Difference} = -182.9 - (-252.87)
\]

This simplifies to:

\[
\text{Difference} = -182.9 + 252.87
\]

Next, perform the addition:

\[
\text{Difference} = 252.87 - 182.9
\]

Calculating that gives:

\[
252.87 - 182.9 = 69.97
\]

So, the difference between the boiling points of oxygen and hydrogen is indeed:

\[
\boxed{69.97}
\]

The initial calculation was correct.
