Answer:
V₂ = 0.958 atm
Explanation:
Given data:
Initial volume = 2300 mL (2300/1000 = 2.3 L)
Initial pressure = 1.88 atm
Final volume = (2.21 L + 2.3L) = 4.51 L
Final pressure = ?
Solution;
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.88 atm × 2.3 L = P₂ × 4.51 L
V₂ = 1.88 atm × 2.3 L / 4.51 L
V₂ = 4.32 atm.L / 4.51 L
V₂ = 0.958 atm
Answer
Aluminum is a silvery-white metal which is extremely soft by nature. Totally earth's crust contains 8% of Aluminum. Aluminium is a low-density nonmagnetic and ductile metal which can be made into sheets or wires as required
Explanation:
Specific heat is the amount of energy needed to increase the temperature per unit mass in 1°C.
The nature of the elements or compounds (metalic elements in this case) determines the transference of heat inside the body of the object. The mechanism of heat transfer inside the metals is conductivty. The more compact and denser the metal, the closer the atoms and the faster the transference of heat by conductivity and the lower the specific heat.
Then, the reason why specific heat of Al is much lower than gold, is that gold is much denser than Al.
