Q1. Consider the following statements in respect of a jet engine and a rocket:
1. A jet engine uses the surrounding air for its oxygen supply and so is unsuitable for motion in space.
2. A rocket carries its own supply of oxygen in the gas form, and fuel.
Which of the statements given above is/are correct?
1. A jet engine uses the surrounding air for its oxygen supply and so is unsuitable for motion in space.
2. A rocket carries its own supply of oxygen in the gas form, and fuel.
Which of the statements given above is/are correct?
Explanation
Statement 1 is correct: A jet engine relies on the oxygen in the Earth’s atmosphere for combustion. In space, where there is no atmosphere, a jet engine cannot function because it cannot obtain the necessary oxygen for burning fuel.
Statement 2 is incorrect: Rockets do carry their own supply of oxygen, but typically, the oxygen is not in gas form. It is usually stored as a liquid oxidizer (e.g., liquid oxygen, LOX) along with the fuel.
