For a proper discussion of the three phases of matter, we require a three-dimensional diagram in which P, V and T should be plotted against three mutually perpendicular coordinate axes. This diagram, known as P-V-T diagram, is difficult to draw on paper. Hence, we gene..

Uses of Gold leaf Electroscope
To detect a charge on a rod 'A' or 'B' bring the rod near to the metallic disc or cap of the electroscope. In either case the leaf diverges as shown in the diagram..
Photocells and their Application
A photocell converts the change in the intensity of light into a change in the electric current. The diagram shows a photocell circuit. The cathode is made of photosensitive materia..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
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.
I like the way this tutors double check the work with me and took time to explain each detail. It really helped me to better understand - Harry
