Sia ? 3 years, 7 months ago

These “things” can be categorized into two different types – Living and Non-living Things. All living things breathe, eat, grow, move, reproduce and have senses. Non-living things do not eat, grow, breathe, move and reproduce. They do not have senses.

We can many things around us . But have you ever wondered Why only some things can move ,reproduce and can grow ? This is because not all the things are same. Yes everything you See around are divided into two groups. They are living things and nonliving things . Difference between living things and non living is that the living things can talk , move and reproduce and nonliving things can't.

The term living thing refers to things that are now or once were alive. A non-living thing is anything that was never alive. In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt.

Blast a hidrojon peroxide

Iron rust in the pump triggered a decomposition explosion of hydrogen peroxide. As the pH was 8.8, more dodecylbenzenesulfonic acid was added and hydrogen peroxide water (60%) was supplied as a bleaching agent from the pump. Then, an explosion occurred near the pump.

1Thank You

Yuvraj Gupta 3 years, 6 months ago

Although pure hydrogen peroxide solutions are not usually explosive at atmospheric pressure, equilibrium vapor concentrations of hydrogen peroxide above 26 mol per cent (40 weight per cent) become explosive in a temperature range below the boiling point of the liquid.

A flower and tree are also living things. Plants are living things and they need air, nutrients, water, and sunlight. Other living things are animals, and they need food, water, space, and shelter. ... Non-living things include things that do not need food, eat, reproduce, or breathe.

Yuvraj Gupta 3 years, 6 months ago

Wind is air in motion. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind: speed and direction.
