SCIENCE 10 Getting To Know Gases (Gases Have Mass)

Summary

In this Grade 10 science experiment, students investigate the properties of gases by demonstrating that gases have mass and occupy space. Using three balloons, a digital balance, and a balloon pump, the mass of both deflated and inflated balloons is measured. The results reveal that the inflated balloon is heavier due to the gas inside, proving that gases, like solids and liquids, have mass. This experiment encourages students to observe and understand the tangible nature of gases, reinforcing fundamental principles of matter.

Takeaways

• 😀 Gases have mass, which is proven through a simple experiment.
• 😀 Materials needed for the experiment include three rubber balloons, a digital balance, a balloon pump, and a learning activity sheet.
• 😀 The procedure involves measuring the mass of both a deflated and an inflated balloon.
• 😀 The mass of the deflated balloon is measured first, followed by inflating the balloon and sealing it securely.
• 😀 The mass of the inflated balloon is then measured, and data is recorded after three trials.
• 😀 The mass of the inflated balloon is greater than the mass of the deflated balloon, showing that gas has mass.
• 😀 This result demonstrates that gases, like solids and liquids, are matter that occupy space and have mass.
• 😀 The deflated balloon weighs less than the inflated balloon due to the presence of gas inside the balloon.
• 😀 The purpose of this activity is to confirm that gases are a form of matter.
• 😀 Question prompts ask whether the mass of the deflated balloon differs from the inflated one, and the answer is 'yes.'
• 😀 This activity helps reinforce the concept that gases, like solids and liquids, are matter with measurable properties.

Q & A

What was the objective of the science activity?

The objective was to prove that gases have mass.

What materials were needed for the experiment?

What was the first step in the procedure?

The first step was to measure the mass of the deflated balloon using a digital balance.

What did the second step of the procedure involve?

The second step involved inflating the balloon using a balloon pump and securely sealing the opening.

What was the third step of the procedure?

The third step was to measure the mass of the inflated balloon.

How many trials were conducted in the experiment?

Three trials were conducted, and the data was recorded on the learning activity sheet.

What was the key observation made during the experiment?

The key observation was that the mass of the inflated balloon was greater than that of the deflated balloon.

What does the result of the experiment show?

The result shows that gas is matter that has mass and occupies space.

How did the experiment demonstrate that gases have mass?

The experiment demonstrated that gases have mass by comparing the mass of a deflated and inflated balloon, with the inflated balloon being heavier due to the gas inside it.

What was the conclusion of the experiment regarding gases?

The conclusion was that gases, like solids and liquids, have mass and occupy space.
