A gas occupies a volume of 2.4 L at 14.1 kPa. What volume will the gas occupy at 84.6 kPa?
Naddik [55]

Answer:

  • <u>0.40 L</u>

Explanation:

Boyle's law for gases states that, at constant temperature, the volume and pressure of a fixed amount of gas are inversely related.

Mathematically, that is:

  • PV = constant

  • P₁V₁ = P₂V₂

Here, you have:

  • V₁ = 2.4 L
  • P₁ = 14.1 Kpa
  • P₂ = 84.6 KPa
  • V₂ = ?

Then, you can solve for V₂:

  • V₂ = P₁V₁ / P₂

Substitute and compute:

  • V₂ = 14.1 KPa × 2.4L / 84.6 KPa = 0.40 L ← answer

Why are gamma rays not affected by a magnet as they pass over it?
Assoli18 [71]
Gamma is not affected by both fields because it isnt charged. 

Only alpha and beta ray will be affected because they are charged with positive and negative ions respectively.

In otherwords, <span>Gamma rays are high-energy photons of light, which have zero electric charge. So they are not affected by magnetic fields</span>

Here's a chart. .

If that doesnt help tell me :)
