Answer:
<em>When a balloon deflates air moves out of the balloon </em><em>because the pressure inside the balloon is higher than the pressure outside the balloon.</em>
Explanation:
An inflated balloon has a high pressure region on its inside. Gases always move from a region of high pressure to a region of low pressure. When a balloon is inflated its membrane stretches making it even more porous.
The gas molecules inside the balloon easily diffuse out through this membrane. The diffusion rate may differ depending on the type of gas filled inside the balloon and the material of the balloon. For example helium balloon deflates faster than common air balloon.
This is because helium is a light element and can escape easier than gases like nitrogen and oxygen through the porous membrane of the balloon.
Answer: The correct answer is (C).
Explanation:
Supply function:
Demand function:
S(p)=D(p), price for which supply is equal to demand:
After solving this above equation graphically, we will get the values of p.
1) p =96.236
2) p=( -118.258)
We will reject the negative value of p.
So, the value of p that price for which the supply equals the demand is $ 96.236 
$96.24. Hence, the correct answer is option (C).
