Which of the following substance is a colorless odorless tasteless radioactive gas?

Radon is a radioactive gas that is colorless, odorless and tasteless.

Which fossil fuel is rich in methane?

What is natural gas? Natural gas is a fossil energy source that formed deep beneath the earth’s surface. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4).

What is the end product of burning the fossil fuel and where does it go?

When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.

How is the trapped air in soil beneficial to humans?

In nutrient management, soil aeration influences the availability of many nutrients. Particularly, soil air is needed by many of the microorganisms that release plant nutrients to the soil.

What’s the best nutrients for flowering?

Start using bloom nutrients when buds start forming to make sure your plant gets plenty of Phosphorus & Potassium, which are crucial to bud development. Phosphorus tends to increase the number of flowers, while Potassium helps increase the bulk/weight of flowers.

What nutrient is best for flowering?

Phosphorus, potassium, and calcium are needed for good flowering and fruiting of plants – like these zucchini. Here are some specific plant species and nutrients that are important for their proper growth and development: Garlic – Benefits from phosphorus and potassium for good bulb and root development.

Should I use Cal Mag during flowering?

Well-Known Member. Yes, you can add cal/mag during flowering and no nitrogen doesn’t slow down flowering, in fact you still need roughly a 1-1-1 ratio for first couple weeks of flower. If you are running coco, then you really need cal/mag during all stages of growth.

What is the best nutrients for vegetative stage?

A general rule of thumb is that a vegetative fertilizer should have high nitrogen, low phosphorus, and moderate potassium: for example, 9-4-5. As a plant transitions into flower, taper off the nitrogen and focus on phosphorus and potassium—seek a ratio around 3-8-7, for example.

Should you water Coco everyday?

The frequency of watering depends on the evaporation and the water supply in the COCO. A common rule is; one daily watering is sufficient during the first few weeks under normal circumstances; then increase up to 2 times a day; 2 hours after the lamps have been turned on and 2 hours before they are switched off again.

How do I know if I’m overwatering my plants?

Are You Sure that Plant Needs Water? 5 Signs of Overwatering

  1. Wet and Wilting. It looks wilted, but the soil is wet.
  2. Brown Leaves. If the leaves turn brown and wilt, there is the possibility that you have been overwatering.
  3. Edema. The third sign that your plant has been overwatered is edema.
  4. Yellow Falling Leaves.
  5. Root Rot.

Is overwatering worse than underwatering?

Overwatering causes plants to drown from lack of oxygen, or suffer from root rot and fungus because they can’t dry out properly. Underwatering is equally detrimental to your plants’ health.

What is the gas that comes from the ground?

Radon is a colorless, odorless, radioactive gas. It comes from the natural decay of the radioactive chemical elements uranium or thorium. These elements are found in nearly all soils. Radon gas typically moves up through the ground and comes into homes through cracks in floors, walls and foundations.

How are the gas present in the air harmful for the soil?

Soil gases can diffuse into buildings, the chief concerns among these pollutants are radon which is radioactive and causes cancer and methane which can be flammable at only 4.4% concentration. Gases fill soil pores in the soil structure as water drains or is removed from a soil pore by evaporation or root absorption.

What is the percentage of air in soil?


When did humans start using fossil fuels?


Can humans be used as fossil fuels?

Humans are animals; we’re made up of the same chemicals as those animals which decomposed into what we now call “fossil fuels”. So, yes, our remains could become oil in the far distant future.

Who still uses coal?

What countries are the biggest users of coal? China is the biggest consumer of coal in the world, followed by the United States. The U.S. consumes about 1 billion tons of coal per year. China consumes about 1.6 billion tons for electricity generation and heating.

Who first discovered fossil fuels?

Andreas Libavius

Which fossil fuel has the most widespread use now?


How much fossil fuels are left?

Taking into consideration the current rate of natural gas production and current known natural gas reserves, we have about 52.8 years worth of natural gas reserves left. We will still have gas and coal left by the time oil runs out in 2052.

What country uses the least coal?


What 3 countries consume the most coal?

Coal Consumption by Country

# Country Cubic Feet Per Capita
1 China 3,055.00
2 India 729.54

4 Germany 3,132.70

Which country has the cleanest coal?

Anthracite is found on the east coast in the US, South Africa, Australia, Western Canada, China and Russia. Two-thirds of Russia’s coal reserves are anthracite. Because of its efficiency and thus less carbon and sulphur usage per watt of power, anthracite is also the ‘cleanest’ coal in the world.

Why is brown coal bad?

The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health.

Is black or brown coal better?

Brown coal is not as efficient at burning as black coal (because of its high moisture and low carbon content) and therefore it produces up to 30 percent more greenhouse gas emissions than black coal when used to generate electricity.

What are 4 types of coal?

Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.

What is the cleanest burning coal?
