He total power used by humans worldwide is approximately 15 TW (terawatts). Sunlight striking Earth provides 1.336 kW per square

meter (assuming no clouds). The surface area of Earth is approximately 197,000,000 square miles.
What percentage of the Earth's surface would we need to cover with solar energy collectors to power the planet for use by all humans? Assume that the solar energy collectors can only convert 10 % of the available sunlight into useful power.

Describe the relationship between temperature and particle movement
soldi70 [24.7K]

Answer:

If matter is heated and thus its temperature rises more and more, it can be seen that the particles contained in it move ever faster – be it the relatively free movement of the particles in gases or the oscillation around a rest position in solids. The temperature of a substance can therefore be regarded as a measure of the velocity of the particles it contains. With a higher temperature and thus higher particle

What is the percent magnesium in a sample made of 24g Mg and 70gCl?
seropon [69]

Answer:

Total percent of magnesium in sample = 25.5%

Explanation:

Given:

Mass of magnesium = 24 gram

Mass of chlorine = 70 gram

Find:

Total percent of magnesium in sample = ?

Computation:

Total mass of sample = Mass of magnesium + Mass of chlorine

Total mass of sample = 24 gram + 70 gram

Total mass of sample = 94 gram

Total percent of magnesium in sample = [Mass of magnesium / Total mass of sample]100

Total percent of magnesium in sample = [24/94]100

Total percent of magnesium in sample = [0.255]100

Total percent of magnesium in sample = 25.5%

During which change of state would the volume of a substance increase the most?
Alika [10]

Answer:

The most state has the high volume is the gas state.

So here the answer is vaporization!!!!

Explanation:

The most state has the high volume is the gas state.

So here the answer is between vaporization and sublimation???

and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas

and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°

here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
