Answer 1

Ответ:

The pitch drop experiment is a long-term scientific experiment that demonstrates the flow of a liquid, specifically pitch, over an extended period of time. In this experiment, a sample of pitch is placed in a funnel and left to slowly drip over several years, showing the highly viscous and elastic nature of pitch. The experiment is famous for its extremely slow rate of flow, with individual drops taking years or even decades to form and fall from the funnel. The most well-known pitch drop experiment is the one at the University of Queensland in Australia, which has been ongoing since 1927.

Експеримент з краплею дьогтю - це довготривала наукова експеримент, що демонструє потік рідини, зокрема дьогтю, протягом тривалого часу. У цьому експерименті зразок дьогтю поміщається в лоток і залишається повільно крапатися протягом кількох років, показуючи високу в'язку та еластичну природу дьогтю. Експеримент відомий своєю надзвичайно повільною швидкістю потоку, і окремі краплі можуть утворюватися і впадати з лотка протягом років або навіть десятиліть. Найвідоміший експеримент з краплею дьогтю проводиться у Університеті Квінсленду в Австралії і триває з 1927 року.

Answer 2

The pitch drop experiment is a scientific experiment that demonstrates the flow of a highly viscous liquid, such as pitch, over an extended period of time. The experiment involves placing a sample of pitch in a funnel and allowing it to slowly flow over time. The purpose of the experiment is to measure the viscosity of the pitch and observe its behavior as it flows.

Procedure of the Pitch Drop Experiment

The pitch drop experiment typically follows these steps:

1. A sample of pitch is heated until it becomes liquid and is then poured into a funnel. 2. The funnel is positioned over a container or a glass jar. 3. The pitch is left undisturbed and allowed to flow at room temperature. 4. Over time, the pitch slowly drips from the funnel and accumulates in the container. 5. The experiment continues until a pitch drop falls from the funnel, which can take several years or even decades.

Significance of the Pitch Drop Experiment

The pitch drop experiment is significant because it demonstrates the properties of highly viscous liquids and challenges our perception of their flow behavior. It also highlights the concept of viscosity, which is a measure of a fluid's resistance to flow. The experiment showcases the unique properties of pitch, which is an example of a non-Newtonian fluid.

Duration of the Pitch Drop Experiment

The pitch drop experiment is known for its long duration, with some experiments lasting for many years. The longest-running pitch drop experiment, known as the "Pitch Drop Experiment at the University of Queensland," began in 1927 and had its first pitch drop recorded in 1938. Since then, several drops have fallen, with the most recent drop occurring in 2014. The experiment is ongoing, and it continues to capture the interest of scientists and the public alike.

Conclusion

In conclusion, the pitch drop experiment is a fascinating scientific experiment that demonstrates the flow behavior of highly viscous liquids. It involves observing the slow flow of pitch over an extended period of time. The experiment highlights the unique properties of pitch and provides insights into the concept of viscosity. The duration of the experiment can span several years or even decades, making it a captivating and ongoing scientific endeavor.
