<h2>Relative Humidity</h2>

Explanation:

  • Humidity is the amount of moisture content present in the atmosphere.

    Humidity is of two types:

  1. Absolute humidity.
  2. Relative humidity.
  • Absolute humidity is the ratio of  the amount of moisture content in the air to the unit volume of the air.
  • Relative humidity can be derived as the ratio of moisture content in the air to the maximum amount of moisture that the air constitutes.
  • Hence, the required answer is Relative humidity.

Answer:

The answer is "= 0.078 \ kg \ H_2".

Explanation:

calculating the moles in CH_4 =\frac{PV}{RT}

                                                =\frac{(0.58 \ atm) \times (923 \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(232^{\circ} C +273)}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (0.0821 \frac{L \cdot atm}{K \cdot mol})(505)K}\\\\=\frac{(535.34 \ atm \cdot \ L) }{ (41.4605 \frac{L \cdot atm}{mol})}\\\\= 12.9 \ mol

Eqution:

CH_4 +H_2O \to  3H_2+ CO \ (g)

Calculating the amount of H_2 produced:

= 12.9 \ mol CH_4 \times  \frac{3 \ mol \ H_2 }{1 \ mol \ CH_4}\times \frac{2.016 g H_2}{1 \ mol \ H_2}\\\\= 78 \ g \ H_2 \\\\= 0.078 \ kg \ H_2

So, the amount of dihydrogen produced = 0.078 \frac{kg}{s}

Answer:

it goes to a solid to a liquid

Explanation:

When something is a solid the molecules are impact together and have a small sense of vibration. But as the solid melts away for example ice, the molecules become more loose forming into a liquid

hi, 100 points, , will also mark brainly-ist (what's the boiling point of water) ((you don't need to answer that))​
BaLLatris [955]

Answer:

212 degrees F, and 100 degrees C.

Explanation:

If the temperature is held constant (which requires some heat input, since evaporation cools things) the liquid will all evaporate. If the temperature is much above 212 F, the water will boil. That means that it wont just evaporate from the surface but will form vapor bubbles, which then grow, inside the liquid itself.   :)
