Electricity, Heating, Magnetic Effects Summary
Summary - Electric potential is the condition that determines the flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit of positive charge from infinity to that point. Electrical potential is a scalar quantity. The po..
Climatic Factors - Temperature
o C to 9 o C. The metalimnion or thermocline which has rapid temperature changes between 9 o C to 21 o C. In the terrestrial environment the seasonal and daily fluctuations in temperature are varied and marked. The lowest temperature recorded for any lan..

Determination of Enthalpy Change ( D H) - The calorimeter is kept open to the atmosphere in the determination of change in enthalpy of a reaction. The calorimeter is immersed in an insulated water bath fitted with stirrer and thermometer. The temperature of the bath is..
Types of Environmental Changes
Environment of earth includes the whole of atmosphere, hydrosphere as related to biosphere. Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - their storage and flow and ..
Change in the Rainfall Patterns
The rainfall patterns in the world are governed by differential heating of air layers over different latitudes. Differential heating of air is the main reason for different convectional air current movement from one part of globe to other. The rainfall is associated with these ..

Conditions For Chemical Change
The criterion for a chemical change is the production of one or more new substances. Therefore, certain conditions should be met in order to bring about a chemical change. The necessary conditions are: 1) A minimum amount of energy needed to initiate a reaction (activation energ..
Internal Energy Change
E gives the change in internal energy. If the internal energy of the products is less than the internal energy of the reactants, then D E would be negative. D E = E p - E r = -ve (Ep < Er) If the internal energy of the products is more than the internal energy of the reactants, th..

Best tutor ever. I can actually understand what to do in fraction and decimal division situations
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Thank you very much for helping to me is very important to have my lessons. Because you manage to take good notes in school thank you Tutor Vista
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
