Melting (solid to liquid)
The answer is 98ppm.
The ppm (Parts per million) is also a concentration unit. 1 ppm is equivalent to 1mg/L
Now, concentration of the solution of sulfuric acid is 0.0980 g/L.
We rewrite, 0.0980 g = 0.0980*1000 mg = 98mg
Therefore, the concentration of the sulfuric acid solution is 98 mg/L = 98 ppm.
Answer:
A.Because Earth's atmosphere causes most objects to burn up before they reach the surface.
Explanation:
The Earth's surface is rarely impacted by large objects that enters because the atmosphere causes most of the objects to burn up before they reach the surface.
There are different layers of the earth atmosphere which carries various amount of energy and energetic particles.
- When a massive and a high solar object or dust or rocks are directed towards the earth, they are either deflected or burnt upon their passage through the atmosphere.
- These energetic particles have ionizing properties and causes the solar particles to burn up.
- This way the earth's surface is shielded from any impact of any sort.
