Answer:
Pumice is a light colored, porous igneous rock. It forms during volcanic eruption occurring under water. It is an aggregate of concrete. Because of their porous nature they float over the surface of water. With time the pumice rocks undergoes with several changes including weathering, erosion, and transportation. The extent of heat and pressure, making the sediments of the pumice rocks into metamorphic rocks distinct in the chemical and physical composition of the parent material.
15% = 15 grams of solute in 100 mL solution
15 g --------------- 100 mL
?? ------------------ 1000 mL
1000 x 15 / 100 =
15000 / 100 => 150 g of solute
hope this helps!
Answer:
According to Kinetic Molecular theory, Temperature is directly proportional to the Average Kinetic energy of a molecules.
Explanation:
If the mass of the particles in a container is constant, then its moving molecules cause the gas gets warmer. On collision of molecules, Kinetic energy of molecules get high, so as a result, temperature gets high.
Fast moving of particles increases the temperature.
