What phase change is the following substance undergoing?
Dvinal [7]

Answer:

b melting

Explanation:

The phase change the substance is undergoing is from solid to liquid and this is called melting.

  • To understand this process, we need to know the the substance changing.
  • A substance that contains particles that are not easily compressed and packed is a solid.
  • Solids have fixed shapes and volumes.
  • Liquids can easily flow although they cannot also be easily compressed.

The phase change from solid to liquid is facilitated by a melting process.

A container of gas occupies 3.5 L at 585 mmHg. What would the new pressure be if the volume decreases to 2.0L?
kodGreya [7K]

Answer:

1023.75mmHg

Explanation:

V1 = 3.5L

P1 = 585mmHg

V2 = 2.0L

P2 = ?

To solve this question, we'll require the use of Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature is kept constant.

Mathematically,

V = kP, k = PV

P1 × V1 = P2 × V2 = P3 × V3 = .......= Pn × Vn

P1 × V1 = P2 × V2

Solve for P2,

P2 = (P1 × V1) / V2

P2 = (585 × 3.5) / 2.0

P2 = 2047.5 / 2.0

P2 = 1023.75mmHg

The final pressure of the gas is 1023.75mmHg
