1. Woolen clothes check our body-heat from going outside and thus keep our body temperature normal.

2. The thought power is the most prominent power.

3. Issac Borne located the lost and submerged ship in the Pacific Ocean by focussing his thought power.

4. Through mental concentration, one can see extra-sensory things and can know about coming events.

5. Paragons are born by awakening the hidden powers of the mind.

• Partial dryness 
• Insufficient availability of O₂
• Lack of facilities for the removal of oxygen.

When the sky is cloudy, during the rain and night time we can not use solar panels.

a. To increase the availability of oxygen. 

i. Increase the surface area exposed to air 

ii. Make available the temperature needed for burning.

b. Sufficient oxygen is made available which increases the rate of combustion. 

c. Partial combustion pollutes the air by giving excess of smoke, soot, carbon monoxide an carbon dioxide.

If you are convinced that there is a gas leak, disconnect electricity from outside the home (switch off the main switches). Switch off the regulator and shift the cylinder to an empty space. Keep the windows and doors open. Request help from the Fire Force by calling in the toll-free number 108.

Well trained rescue operators can put out the fire by covering the top end of the cylinder with wet sack to prevent the contact with oxygen. If the fire is in flat or the top story, then one should not try to escape using lifts. Only staircase should be used. Cover the nose and the mouth with soft cloth to avoid the intake of smoke or gases.

In a solar panel light energy is converted into electrical energy.

Methane gas is responsible for the putrid smell.

When energy is transformed from one form to another, some part of it gets lost in other forms. Such a loss is the main cause for energy crisis.

Solar water heating (SWH) is the conversion of sunlight into heat for water heating using a solar thermal collector. A sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (convection driven). They use water only, or both water and a working fluid. They are heated directly or via light-concentrating mirrors. They operate independently or as hybrids with electric or gas heaters. In large- scale installations, mirrors may concentrate sunlight into a smaller collector.

• Soil contamination 
• Air contamination 
• Water contamination 
• Bad impact on human health 
• Impact on animals and marine life. 
• Disease-carrying pests 
• Adversely affect the local economy 
• Missed recycling opportunities.

From different sources like sun, fuels and power stations.

• Solar panel 
• Solar water heater 
• Solar cooker 
• Solar water heater 
• Solar thermal power plant

• Muscular energy – for different physical activities
• Chemical energy – for cooking
• Mechanical energy – for moving
• Sound energy – to call friends.

Nuclear Fusion is carried out in stars.

In Kerala usually, waves are of low. So they have less energy. Also during tides Kerala sea coasts, the sea attitude does not increasingly rise.

We use fossil fuels like petrol or diesel in cars. The plants which lived millions of year ago have also used solar energy for photosynthesis to make food. Humans and animals grew up by taking these plants and fruits. Then this humans and animals are burned in earth after their death and became fossil fuels. Fuels are formed out of them. This fuel is being used in cars so the ultimate source of energy here is the solar energy itself. The vehicles connected with solar panels uses solar energy in the direct form.

a. Plants and animals that went under the earth many years ago changed into fossil fuels by undergoing changes under high pressure, high temperature, and absence of oxygen. 

b. Carbon 

c. Ammonia, coal gas, coal tar, coke 

d. The greenhouse gases given out by the burning of fossil fuels increase the temperature of atmosphere and causes global warming

Oxygen is used along with hydrogen to make Hydrogen fuel cells.

Enriched Uranium

Kerala is a highly populated state in India. Therefore there are not much vacant places available for the construction a nuclear reactors here. Since the radiations given out from such power plant are very harmful to human life, it may cause unpredictable effects. I strongly disagree with this opinion.

LNG – liquefied natural gases can be conveniently transported by liquefaction. Can be changed into gaseous state at the same temperature and can be distributed through pipes.

a. Hydrogen easily catches fire and has a high chance of explosion. It is difficult to store and transport. 

b. Oxygen.

Solar energy is a renewable energy source.

Renewable energy resources – Solar energy, Geothermal energy, Coal

a. Biogas is formed in the biogas plants by the action of bacteria on biomass in the absence of oxygen. 

b. Biogas has higher calorific value; environmental pollution is less. 

c. Community biogas plants help in controlling environment pollution, centralised energy source minimizes expense.

One of the mRNA sequences (UAA, UAG, UGA) that signals the termination of translation. A codon for which no normal tRNA molecule exists. The presence of a nonsense codon causes termination of translation (ending polypeptide chain synthesis). There are three nonsense codons are called amber(UAG) ochre(UAA) and opal (UGA).

B) It helps the plant to maintain temperature in hot sunny days.
