Answer:

Explanation:
Question 7.
We can use the Combined Gas Laws to solve this question.
a) Data
p₁ = 1.88 atm; p₂ = 2.50 atm
V₁ = 285 mL; V₂ = 435 mL
T₁ = 355 K; T₂ = ?
b) Calculation

Question 8. I
We can use the Ideal Gas Law to solve this question.
pV = nRT
n = m/M
pV = (m/M)RT = mRT/M
a) Data:
p = 4.58 atm
V = 13.0 L
R = 0.082 06 L·atm·K⁻¹mol⁻¹
T = 385 K
M = 46.01 g/mol
(b) Calculation

Yes becuase it says it maintains its velocity if it is moving or at rest
Answer:
There is no way of finding the volume of an irregular shape.
We cant find the volume of an irregular solid because we can never measure the volume of curves that are present in an irregularly shaped object. so we tend to place this irregular object in a beaker of water so that the volume of water displaced by it will actually show us the volume of object itself. And now we can conclude that water displacement is an effective way of measuring the volume of an irregular solid there is no way of finding the volume of an irregular shape.
