Question

Если в опыте торричелли ртуть в чашке заменить водой, можно ли измерить атмосферное давление? Объясните, что произойдёт СРОЧНО!!!! дам 30 балов!!!

Answer 1

Ответ: можно)

Объяснение:

В данном случае необходимо будет заменить не только ртуть на воду , а это вполне возможно (такой водный барометр соорудил на площади великий Ньютон еще в 17 веке), но и длину трубки. Т.к. плотность воды в 13,6 раза меньше плотности ртути, то под действием атм. давления вода  способна подняться на  высоту , равную  13,6 *0,76 м= 10,34 м. Вот такое сооружение и построил Ньютон, а жители города с интересом наблюдали за атм. давлением.

Answer 2

Can atmospheric pressure be measured if water is used instead of mercury in the Torricelli experiment?

Yes, atmospheric pressure can still be measured if water is used instead of mercury in the Torricelli experiment. The Torricelli experiment, also known as the barometer experiment, was originally conducted using mercury. However, the principle behind the experiment remains the same regardless of the liquid used.

In the Torricelli experiment, a glass tube is filled with a liquid (usually mercury) and then inverted into a container filled with the same liquid. The liquid in the tube will fall until it reaches a certain height, creating a vacuum above it. The height of the liquid column is directly proportional to the atmospheric pressure.

If water is used instead of mercury in the experiment, the same principle applies. The water column in the tube will fall until it reaches a certain height, creating a vacuum above it. The height of the water column can then be measured and used to determine the atmospheric pressure.

It's important to note that the height of the water column will be significantly greater than that of the mercury column due to the difference in density between water and mercury. Water is less dense than mercury, so a taller column is needed to balance the atmospheric pressure.

In summary, by using water instead of mercury in the Torricelli experiment, it is still possible to measure atmospheric pressure. The height of the water column in the inverted tube can be measured and used to determine the atmospheric pressure.
