Answer:
Thermospheric temperatures increase with altitude due to absorption of highly energetic solar radiation. ... Radiation causes the atmosphere particles in this layer to become electrically charged particles, enabling radio waves to be refracted and thus be received beyond the horizon.

Answer:
using charles law , volume of gas is 525.7 L
Explanation:
Charles law states for a fixed mass of gas the volume is directly proportional to absolute temperature at constant pressure.
V1 / T1 = V2 / T2
V1 is volume and T1 is temperature at first instance
V2 is volume and T2 is temperature at second instance
substituting the values in the equation
480 L / 315 K = V2 / 345 K
V2 = 525.7 L
therefore new volume is 525.7 L
SI unit of length - meters
Answer:
<h2>The answer is 28.2 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of table = 12 cm³
density = 2.35 g/cm³
The mass of the table is
mass = 2.35 × 12
We have the final answer as
<h3>28.2 g</h3>
Hope this helps you
Answer:
294 moles of P
Explanation:
For every 1 mol of P4O10 contains 4 mol of P
so;
73.5 mol P4O10 × <u> </u><u> </u><u> </u><u> </u><u> </u><u>4 mol P</u><u> </u><u> </u><u> </u><u> </u><u> </u>
1 mol P4O10
= 73.5 × 4
= 294 moles of P
