Answer 1

To find the difference between the boiling point of oxygen and hydrogen, you subtract the boiling point of hydrogen from the boiling point of oxygen.

The boiling point of oxygen: \(-182.9\) °C
The boiling point of hydrogen: \(-252.87\) °C

Now, calculate the difference:

\[ -182.9 - (-252.87) = -182.9 + 252.87 \]

Now perform the calculation:

\[ 252.87 - 182.9 = 69.97 \]

Thus, the difference between the boiling point of oxygen and hydrogen is \(69.97\).

Enter your answer as a decimal value: 69.97.

Answer 2

is that correct

Answer 3

Let's verify the calculation step by step:

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 calculate:

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

This gives us:

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

This simplifies to:

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

Now, calculating this:

\[ 252.87 - 182.9 = 69.97 \]

So, the difference is indeed \(69.97\).

Final answer: 69.97 is correct.

Answer 4

In September, Claire weighed 187.4 pounds. By March, she weighed 163.5 pounds. What integer represents the change in Claire’s weight?

Answer 5

To find the change in Claire's weight, you subtract her weight in March from her weight in September.

1. Claire's weight in September: 187.4 pounds
2. Claire's weight in March: 163.5 pounds

Now, calculate the change in weight:

\[ \text{Change in weight} = \text{Weight in September} - \text{Weight in March} \]

Substituting the values:

\[ \text{Change in weight} = 187.4 - 163.5 \]

Now, perform the calculation:

\[ 187.4 - 163.5 = 23.9 \]

Thus, the change in Claire’s weight is 23.9 pounds.

Enter your answer as a decimal value: 23.9.
