The solubility of a solid in a liquid generally increases with the rise in temperature but hardly changes with the change in pressure. However, the extent of increase in solubility depends upon the nature of the solid. For substances such as calcium sulphate and calcium acetate, the solubility decreases with the rise in temperature. In general, the solubility of those substances which dissolve with the absorption of heat (endothermic process), increases with rise in temperature. On the contrary, the solubility of those substances which dissolve with the evolution of heat (exothermic process), decreases with rise in temperature.
The solubility of a gas in a liquid decrease with the rise in temperature, but increases with the increase in pressure.

My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
