The new volume is mathematically given as
V2= 16.12 L
<h3>
What is the new volume?</h3>
Question Parameters:
A sample of gas has an initial volume of 20 L
and an initial pressure of 2.5 atm.
If the pressure changes to 3.1 atm
Generally, the equation for Pressure is mathematically given as
P1V1 = P2 V2
2.5 * 20 = 3.1 * V2
V2 = 50/3.1
V2= 16.12 L

Answer:
636 balloons
Explanation:
If we assume that helium gas follows an ideal gas behaviour, we can use the ideal gas law to solve this problem as follows:
- We consider two different states, the initial given by the conditions of the problem statement and the final, when the tank reaches atmospheric pressure and it's no longer able to fill balloons:
- To find out what would be this volume 2, we use the Boyle's Law:
- Now we find the available volume to fill the balloons by substracting both, volume 2 and volume 1:
- Finally, we determine the quantity of ballons by dividing that available volume between the volume of each ballon:
Water is the answer hope this helps
Answer:
Explanation:
In a chemical change through chemical reactions, a new kind of matter forms. When a paint is mixed together, a physical change has occurred and not a chemical change. The different color one perceives is just a mere overlap between the reflected white and red color which produces another hue.
Not all color changes infers a chemical reaction. A paint is a complex mixture on its own.
