This is easy as you only need Boyle's Law to answer these problems. Boyle's law is expressed as : P₁V₁ = P₂V₂For number 1, we are looking for P₂. To get P₂, you first need to identify the given and find V₂. To get V₂, multiply V₁ (1.5 L) with 1/2.V₂ = 1/2 * V₁ = 1/2 * 1.5 L = 0.75 Lfollowing the formula of Boyle's Law :(0.95 atm) * (1.5 L) = P₂ * (0.75 L)Now, let's solve for P₂:P₂ = (0.95 atm * 1.5 L) / 0.75 LP₂ = 1.425 atm / 0.75P₂ = 1.9 atmFor number 2, we are looking for P₂.1.01⋅6.00=P⋅3.006.06=P⋅36.06=3PDivide both sides by 36.06/3=3P/3P= 2.02 atmHope this helps!- Sam <3
