Correct Answer: 1, 2 and 3

Gobar gas is produced by the __________ of ‘gobar’ (cow dung).

Gobar gas is produced by the __________ of 'gobar' (cow dung).

Consider the following statements regarding the energy from biomass.
1. Biomass is a plant matter produced as a result of photosynthesis and some of it can be burnt to provide heat. For example, wood and agricultural waste.
2. Biomass can also be used for power generation or converted into alcohol (liquid or methane gas) to be used as fuel.
3. Biomass is renewable energy and shall be available as long as plants growon Earth.
Which of the above statement(s) is/are correct?

In the following question, two statements are given each followed by two conclusions I and II. You have to consider the statements to be true even if theyseem to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements. Statement:
(I) Life is a journey with few known people, few partially known and mostly strangers.
(II) In a journey, the importance of destination is as equal as the pathway of reaching that destination. Conclusions:
(I) Importance of people in life is considerable, as they are our journey mates.
(II) Life teaches us many lessons to face various known and unknown difficulties.

A process is carried out for the feed mixture of 50% air and 50% methane vapor, the compressor recovered 20% of methane, what is the exit pressure of the compressor, if the partial pressure of methane vapor is 25 mm Hg?

Intake air containing 0.2% methane enters a section of an underground mine where emission of methane is 0.05m3/s. Assuming that the threshold limit value of methane is 1.25%, the minimum quantity of fresh air required in m3/s is

Consider the following statements.
1. Methyl alcohol is also called wood spirit because in early stage it was prepared by the destructive distillation of wood.
2. Ethyl alcohol is also called grain alcohol because it is obtained by the starch enriched substance.
3. Rectified spirit is also called commercial alcohol.
Which of the statements given above are correct?

Modern civilization is completely dependent on energy, which has therefore to be abundant and also economical. About 85% of the world's energy is supplied by oil, coal and natural gas while nuclear, hydro, wind and solar power and biomass supply the rest. Coal, nuclear and hydro are used primarily to generate electricity while natural gas is widely used for heating. Biomass is used both for heating and cooking. The wind and solar power is the future's hope as they are sustainable energy sources. Oil powers almost all machines that move and that makes oil uniquely versatile. Oil powered airplanes carry 500 people across the widest oceans at nearly the speed of sound. Oil powered machines produce and transport food. Oil powered machines are ubiquitous. Clearly, we live in the age of oil but it is drawing to a close. According to data available if oil production remains constant until it's gone, there is enough to last 42 years. Oil wells will produce less as they become depleted, which will make it impossible to keep production constant. Similarly natural gas and coal will last another 61 years and 133 years respectively. Naturally, as they become scarce, they become expensive, leading to a worldwide energy crisis. If we are to survive on this planet, we have to make a transition to sustainable energy sources. The transition may be willy-nilly or planned - the choice is ours. The dawning era of limited and expensive energy will be very difficult for everyone on earth but will be even more difficult if it is not anticipated. It is of utmost importance that the public and policymakers understand the global energy crisis and act in tandem to ensure that the species 'homo sapiens' does not become extinct.
