Question

Как экспериментально доказать что воздух имеет массу и вес

Answer 1

Самый простой опыт узнать то, что у воздуха есть вес - это уравновесить на весах две емкости с воздухом (к примеру, две банки с плотными стенками и крышками).

После чего из одной емкости воздух откачать. Можно даже не до состояния вакуума, а просто добиться существенного разрежения.

Весы убедительно покажут - вес банки с воздухом выше, чем у той, в которой воздуха нет.

Answer 2

Experimental Evidence for the Mass and Weight of Air

To experimentally demonstrate that air has mass and weight, we can perform a simple experiment involving the displacement of air and the measurement of its effects. Here's a step-by-step explanation of the experiment:

1. Materials Needed: - A container with a known volume, such as a balloon or a syringe. - A balance or scale to measure mass. - A ruler or measuring tape to measure volume. - A vacuum pump (optional).

2. Procedure: 1. Start by weighing the empty container to determine its mass. 2. Inflate the container with air, ensuring that it is completely filled. 3. Measure the volume of the container by using a ruler or measuring tape to determine its dimensions. 4. Weigh the container again, this time with the air inside. 5. Calculate the mass of the air by subtracting the mass of the empty container from the mass of the container with the air inside. 6. Calculate the weight of the air by multiplying the mass of the air by the acceleration due to gravity (approximately 9.8 m/s^2).

3. Results and Analysis: - The experiment should demonstrate that the container with the air inside has a greater mass and weight compared to the empty container. - This provides evidence that air has mass and weight.

It's important to note that the experiment described above is a simplified demonstration. In reality, air is a mixture of different gases, and its properties can vary depending on factors such as temperature and pressure. However, this experiment provides a basic understanding of the mass and weight of air.

Please keep in mind that the experiment described above is a general approach. There may be variations or additional steps depending on the specific setup or equipment used.
