Location: Delhi, India
• Total Experience:
1 Year
Tutoring Experience :

Currently I am studying at Hansraj College, Delhi University. I like to teach children as teaching is my hobby. I have very good understanding of Mathematics, Physics and Geography. I have been in a school for 4 months as a Maths teacher.

Tutoring Option :
Home Tuition Only
Tutoring Approach :
I want to spread knowledge more than the subject to students. I approach tutoring in such a way that I show the students the basics, and then give them a variety of practice exercises and urge them figure out the answers themselves. If in doubt, I would keep prompting them to find the right answers thereby helping them to grasp the right concepts.

• Question: What is the difference between Dam and barrage?

Posted in: Geography | Date: 02/01/2016

A weir is an impervious barrier constructed across a river to raise the water level on the upstream side. The water is raised up to the required height and the water then flows over the weir. In a weir the water overflows the weir, but in a dam the water overflows through a special place called a spillway. Weirs have traditionally been used to create mill ponds. They are also used to prevent flooding, measure discharge, and help render a river navigable.

The crest of an overflow spillway on a large dam is often called a weir. Weirs can be built of wood, concrete or moraine material (rocks, gravel, boulders). Small weirs are used many times as one possible mitigation measure in large hydropower developments, along with fish ladders, fish stocking and substrate improvement because low weirs can improve fish recruitment, stabilize groundwater levels and lessen the effects of river regulation that often accompanies very large hydro projects. Small weirs usually have positive benefits on winter fish survival, increased biodiversity and the landscape aesthetics. However, they can also can result in increased sedimentation, changes in the fish community and can pose migration barriers.

A barrage is a weir that has adjustable gates installed over top of it, to allow different water surface heights at different times. The water level is adjusted by operating the adjustable gates. A dam is a high impervious barrier constructed across a river valley to form a deep storage reservoir. The surplus water is not allowed to flow over the dam, but it flows through the spillways provided at some level built into the dam.

• Question: What are the characteristics of desert vegetation?

Posted in: Geography | Date: 02/01/2016

When you imagine a desert, what do you think of first? Maybe it’s sand, heat or Gila monsters, but most likely it’s a cactus. Cacti are probably the most memorable characteristic of the desert.

Many desert plants have made adaptations or changes that help the plants to survive in an environment with little water. Desert plants have two main adaptations: • The ability to collect and store water • Features that reduce water loss.

relative term - transitions occur latitudinally with more xeric thorn forests and with grass savannas.

what are deserts? - subtropical arid regions where potential evaporation (>2000mm) is >> annual precipitation (<200mm)

• Question: Why is bond enthalpy of fluorine is lower than that of chlorine?

Posted in: Chemistry | Date: 03/01/2016

It is because of small size of flourine, F has highest electronegativity so the inner electronic repulsion occurs ....so it has lower than chlorine, which has greater size and lower electronegativity also

• Question: What is specific conductance of a solution and what is its unit?

Posted in: Chemistry | Date: 03/01/2016

Conductance is a measure of ability of an solution to conduct electricity but specific conductance is how well water conduct an electric current. The unit of specific conductance is simens/meter (S/m)

• Question: How can chloroform be obtained from ethanol?

Posted in: Chemistry | Date: 03/01/2016

It is a chain reaction, the mechanism of this reaction is SN1, here we can replace Cl by OH a good leaving group, but if we mix Cl in excess then chloroform will form

• Question: What are polyesters?

Posted in: Chemistry | Date: 03/01/2016

Fatty acids are long chain carboxylic acids and the by the reaction of alcohol and carboxylic acids forms a ester ....then the long chain esters we get from this process, the combination of more than 2 ester functional groups called polyester

• Question: Name the functional groups that distinguish glucose and fructose.

Posted in: Chemistry | Date: 03/01/2016

Glucose has a aldehyde functional group and fructose has a keto functional group

• Question: What are detergents?

Posted in: Chemistry | Date: 03/01/2016

Detergents are soap like compounds but more soluble in water, mainly these compounds are alkylbenzenesulfonate........

• Question: Give one example of zero order reaction.

Posted in: Chemistry | Date: 03/01/2016

Decomposition of ammonia

• Question: What is the basic principle of paper chromatography?

Posted in: Chemistry | Date: 03/01/2016

Solute solvent extraction

• Question: How can you distinguish between alkane and Alkene?

Posted in: Chemistry | Date: 03/01/2016

Alkane and alkene both are hydrocarbons, alkanes have sigma bond between carbon and carbon, carbon and hydrogen. So alkanes are saturated hydrocarbons, but alkenes have double bond in chain, it can be one or two or three in a chain....so alkenes are unsaturated hydrocarbons. That's the difference of double bond and single bond....single bond means only sigma bond but double bond means sigma bond with pi bond ...

• Question: What is the main difference between real and ideal gas? How was it rectified wit...

Posted in: Chemistry | Date: 03/01/2016

Ideal gas are gases which follow the ideal gas rule PV = nRT but real gases doesn't follow the ideal gas rule. This ideal gas rule consists of charles and Boyle's law

• Question: Which test is used to differentiate between aldehyde and ketone?

Posted in: Chemistry | Date: 03/01/2016

Shiff reagent and fehling reagent tests Ketone is good oxidative agent so it doesn't give these test but aldehyde gives these test

• Question: What are Van der waals forces? Where do these act?

Posted in: Chemistry | Date: 03/01/2016

Van der waal forces are instantaneous dipole dipole interaction, these forces are too shortrange and weakest forces.... When the interaction between two dipoles occurs then vander waal force occurs
