Answer:
80.2L
Explanation:
Given parameters:
Initial volume of oxygen = 47.2L
Initial pressure of oxygen = 1240torr
Final pressure = 730torr
Unknown:
Final volume = ?
Solution:
To solve this problem, we apply the Boyle's law proposed by Robert Boyle. It states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states
1240 x 47.2 = 730 x V₂
V₂ = 80.2L
what is different about these two different foxes is the fox in Florida looks like he is on a diet of plants. The fox in wyoming looks like he has a squirel or some kind of animal in his mouth. Also their environment that they live in is completely different from each other hope it helps
Explanation:
Answer: The given statement is true.
Explanation:
Boiling point is defined as the point at which vapor pressure of a substance becomes equal to atmospheric pressure. During this point, the liquid changes into vapor state and temperature remains constant till all the liquid changes into vapor state.
Vapor pressure is defined as the pressure exerted by vapors or gas on the surface of a liquid.
Thus, we can conclude that the statement if the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil, is true.
You want us to answer all that and only get 5 points that’s not fair :(
