Answer:

(a) The final pressure of the sample becomes one-fourth of the original pressure.

(b) The pressure of the sample remains unchanged.

(c) The final pressure of the sample becomes four times of the original pressure.

Explanation:

(a)

P_{2}=\frac{P_{1}V_{1}T_{2}}{T_{1}V_{2}}

The volume of sample doubled and kelvin temperature halved.

V_{2}=2V_{1}

T_{2}=\frac{1}{2}T_{1}

P_{2}=\frac{P_{1}\times V_{1}\times \frac{1}{2}T_{1}}{T_{1}\times2V_{1}}=\frac{P_{1}}{4}

Therefore, the final pressure of the sample becomes one-fourth of the original pressure.

(b)

Volume and temperature of sample doubled.

V_{2}=2V_{1}

T_{2}=2T_{1}

P_{2}=\frac{P_{1}\times V_{1}\times 2T_{1}}{T_{1}\times2V_{1}}={P_{1}}

Therefore, the pressure of the sample unchanged.

(c)

Volume of sample halved and temperature double.

V_{2}=\frac{1}{2}V_{1}

T_{2}=2T_{1}

P_{2}=\frac{P_{1}\times V_{1}\times 2T_{1}}{T_{1}\times \frac{1}{2}V_{1}}={4P_{1}}

Therefore, the pressure of the sample becomes four times of the original pressure.

Problem 1:
WARRIOR [948]

Answer:

12,302.59 mL

Explanation:

The problem above requires the conversion of the unit of volume, <em>gallon</em>, to <em>milliliter. </em>

You have to take note of the following values before computing.

  • 1 L is equivalent to 0.264172 gallons
  • 1 L is equivalent to 1,000 ml

Now, we can do the conversion. Let's convert<u><em> 3.25 gallons to milliliter</em></u>.

1. 3.25 gallons x \frac{1 L}{0.264172 gallons} = 12.30259 L

2. 12.30259 L x \frac{1,000 ml}{1 L} = 12,302.59 mL

Therefore, <u><em>3.25 gallons of distilled water is equivalent to 12,500 mL of distilled water.</em></u>

balandron [24]

Answer:

B) weathering and erosion

Explanation:

The two processes responsible for changing metamorphic and igneous rocks into sedimentary rocks is weathering and erosion.

Weathering is the defined as the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Erosion is the removal of weathered materials from the surface of the earth.

The process of erosion and weathering serves to convert igneous and metamorphic rocks into sediments by which a sedimentary rock is formed.
