The volume of air in a person's lungs is about 615 ml, at a pressure of 760 mm Hg. Inhalation occurs when the pressure in the lungs drops to 752 mm Hg. To what volume do the lungs expand?
Answer:
621.5mL
Explanation:
Given parameters:
Initial volume = 615mL
Initial pressure = 760mmHg
Final pressure = 752mmHg
Unknown;
Final volume = ?
Solution:
To solve this problem, we simply apply Boyle's law.
"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 the pressure
1 and 2 are the initial and final states
Now insert the parameters and start;
760 x 615 = 752 x V₂
V₂ = 621.5mL

This theory was first proposed by Nicklaus Copernicus. Copernicus was a polish astronomer. He first published the heliocentric system in hes book: De revelation erbium comestible, "In revelations of the heavenly bodies," which appeared in 1543. HOPE IT HELP:)
Answer: The dotted line shows a new potential energy diagram with a shorter activation energy hill than that in the original potential energy diagram.
Explanation:
Activation energy is the extra amount of energy required by the reactants to cross the energy barrier to get converted into products.
When a catalyst is added, it lowers down the activation energy which is shown by a dotted line. As now less energy is required, more of reactants can cross the energy barrier and get converted to products and thus increase the rate of reaction.
A catalyst increases the rate of reaction for both exothermic and endothermic reactions.
