volume , density, mass

volume, density, and mass

Today I and my friend do lab they are very fun. We know about volume density and mass. We put rock beaker that full of water then we pour water that over in the tube then we measure the water then we know the density.

Assignment 1
               The impact  of environment on society 3 things 

1.Acid rain: rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forest and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.
2.Global warming: increase in the emission of CO2, from different sources into the atmosphere affects the heat balance of the earth.
3.Ozone Depletion: Ozone layer exists in the stratosphere between 20 to 26 km above the sea level. Ozone layer acts as a shield and protects the earth’s organism from the harmful effects of ultraviolet radiations of the sun.
