Question

A jet plane on a single trip across the Atlantic uses ____ tonnes of oxygen and releases ____ tonnes of CO\({}_{2}\).

• A. 15 and 30
• B. 25 and 50
• C. 35 and 70
• D. 45 and 90

Hint:

This is a standard textbook figure for a single trip across the Atlantic. The CO2 released is double the oxygen used.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Burning aviation fuel uses atmospheric oxygen and gives out carbon dioxide.

Step 2: Recall the figure
A jet plane on one crossing of the Atlantic uses about 35 tonnes of oxygen. It releases about 70 tonnes of \(\text{CO}_2\).

Step 3: Select the option
The pair 35 and 70 is option C.

Final Answer:
A jet uses 35 tonnes of oxygen and releases 70 tonnes of carbon dioxide. \[ \boxed{\text{(C) }\text{35 and 70}} \]
