Question

describe an experiment to show that pressure increases with the decrease in the area of surface​

Answer 1

Answer:

press a baloon against one pin it bursts

but now arrange lot of pins parallel closely to each other if u press a baloon against them it does not burst hope this helps u

Answer 2

The experiment can be of placing the brick on the dough to show pressure increases with the decrease in the area of surface​

• We can take a brick that is 20 by 10 by 5 cm in size. Next, we need tp place some clay in a glass container and make a soft dough by adding water and kneading it.
• One of the brick's 20 cm × 10 cm faces should be in contact with the dough when it is placed on it. We should also keep a track of how far the brick reaches into the dough.
• The brick should be thoroughly cleaned before being positioned on the dough with one of its 10 x 5 cm faces in contact with it. Next, we need to see how far the brick reaches into the dough. Here, the brick penetrates more than it did in the first.
• Therefore, it can be observed that -

1. In the first scenario, a 200 cm² surface area is affected by the brick's weight.
2. In the second scenario, a surface area of 50 cm is affected by the brick's weight.
3. This demonstrates that pressure rises when the surface area is reduced while the applied force remains constant.
