Effect of Temperature
Generally, the rates of chemical reactions increase with increase in temperature. It is a common observation that perishable foods like milk, cooked vegetables decay more quickly in summers than in winter. Consider the chemical reaction: At 273 K, the reaction is extremely..

Oil spill is a major problem in the oceans and seas. The oil tankers and offshore petroleum refineries cause oil leakage into the waters. This pollutes the waters. Oil floats on the water surface and prevents the atmospheric oxygen from mixing in the water. ..
Effect of temperature
The effect of temperature on the behaviour of real gases is studied by plotting the value of 'PV' against temperature. It is observed that the deviations from ideal behaviour is less with the increase in temperature. Thus, real gases show ideal behaviour at ..
Effect of Temperature
A chemical equilibrium involves two opposing reactions. If one of them is exothermic, the other must be endothermic. If a system at equilibrium is subjected to change in temperature, the equilibrium adjusts itself to counteract the effect of the applied change. Thus, if the ..

Argemone oil is a highly toxic oil which when consumed by man can cause a disease called dropsy. To test the presence of this oil in cooking oil, take the sample to be tested in a test tube and add some concentrated nitric acid to it. Shake the tes..
Effect of Temperature on Matter
The temperature effect on heating a solid varies depending on the nature of the solid and the conditions required in bringing the chang..
Effect of temperature on equilibrium
According to the Le Chatelier's principle, when the temperature or heat supplied to a system at equilibrium is increased, the system should move in a direction so that the added heat is absorbed. Thus, an increase in the temperature of a chemical system at equilibrium, favours ..

An optimum temperature ranging from 25 o C to 35 o C is required for a good rate. At temperatures around 0 o C the enzymes stop working and at very high temperatures the enzymes are denatured. Since both the stages of photosynthesis require enzyme activity, the t..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
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
