Below is an attachment containing the solution.
Answer:
The total volume of the air is 1000 cubic centimeters.
Explanation:
Since the bicycle pump and the bicycle tyre have the same pressure, then the total volume of the air is the sum of the volume of each element, then we translate this into the following artihmetical expression:
![V = 200\,cm^{3}+800\,cm^{3}](https://tex.z-dn.net/?f=V%20%3D%20200%5C%2Ccm%5E%7B3%7D%2B800%5C%2Ccm%5E%7B3%7D)
![V = 1000\,cm^{3}](https://tex.z-dn.net/?f=V%20%3D%201000%5C%2Ccm%5E%7B3%7D)
The total volume of the air is 1000 cubic centimeters.
Yes, an increase in temperature is accompanied by an increase in pressure. Temperature is the measurement of heat present and more heat means more energy. Molecules in hotter temperatures move faster and more often, eventually moving into the gaseous phase. The molecules would fill the container, and the hotter it got the more they would bounce off the walls, pushing outward, increasing the pressure.
I suppose you could measure this with some kind of loosely inflated balloon and subject it to different temperatures and then somehow measure the size/pressure of it.
Answer:
1. Recollapsing universe
2. Critical universe
3. Coasting universe
Explanation:
Recollapsing universe has dark matter density greater than critical density. While critical universe has its matter density equal to the critical sensity. Coasting universe on the other hand has much smaller matter density compared to critical density.
Note that the critical density is approximately 10^-20 grams/cm3
