Answer:

A) 100 mL

Explanation:

At constant temperature and number of moles, Using Boyle's law  

{P_1}\times {V_1}={P_2}\times {V_2}

Given ,  

V₁ = 200 mL

V₂ = ?

P₁ = 60 kPa

P₂ = 120 kPa

Using above equation as:

{P_1}\times {V_1}={P_2}\times {V_2}

{60\ kPa}\times {200\ mL}={120\ kPa}\times {V_2}

{V_2}=\frac{{60}\times {200}}{120}\ mL

{V_2}=100\ mL

A 575.4575.4 mL sample of carbon dioxide was heated to 377377 K. If the volume of the carbon dioxide sample at 377377 K is 824.7
Margaret [11]

Answer:

263 K

Explanation:

Assuming ideal behaviour and constant pressure, we can solve this problem by using Charles' law, which states that at constant pressure:

  • T₁V₂=T₂V₁

In this case:

  • T₁ = ?
  • V₂ = 824.7 mL
  • T₂ = 377 K
  • V₁ = 575.45 mL

We <u>input the data</u>:

  • T₁ * 824.7 mL = 377 K * 575.45 mL

And <u>solve for T₁</u>:

  • T₁ = 263 K
