Explanation:
As we know that molecules of a gas move far away from each other because they are held by weak Vander waal forces. So, when a balloon is filled by a gas then molecules of a gas strike at its walls leading to more number of collisions.
This will also lead to more expansion of the balloon. As we know that pressure is the force exerted n per unit area of a substance or object.
Thus, more is the kinetic energy of the molecules of the gas more will be the force exerted by them. Hence, more will be the pressure exerted.
200 is the answer let me know if you need anything
Answer:
1) They are directly proportional
2) They are also inversely proportional
Explanation:
1. as the temperature increases, the pressure also increases. and vice versa.
2. however, as the volume increases, the pressure decreases. and if the volume decreases, the pressure increases.
Answer:
You fill up the 5 liter bottle. Then pour the contents from the 5 liter to the 3 liter till the 3 liter is full. Once the 3 liter bottle is full, what is left in the 5 liter bottle is 2 liters. Then you empty out the 3 liter until it matches the height of the 5 liter. Pour the remaining contents of the 3 liter bottle in the 5 liter bottle to get exactly 4 liters.
