Temperature
Certain chemical reactions do not take place at room temperature but occur readily at a higher temperature. Thus heat is required to start the reaction e.g. fuels like coal and wood only start burning when heated to a certain temperature (ignition ..

I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
Helped without just giving the answer and was patient. Also got straight to the point. That is what I'm looking for…
Explained things very well and made them easy to understand
