Metal Particles
The micro-particles of toxic metals and SO 2 gas present in the polluted atmosphere get adsorbed on metal particles rendering them highly toxic. These are released by various metal-finishing operation..
Particles in matter attract one another
The particles in matter attract one another. This attraction is inversely proportional to the distance between the particles. However, the magnitude of these inter-particle forces differs from one substance to anoth..
Characteristics of Particles of Matter
According to the dynamic particle model all states of matter are made up of tiny particles and matter as a result is an aggregation of very small particles..
Distinction between Wave and Particle
Distinction between Wave and Particle - A particle occupies a well-defined position in space, which cannot be simultaneously occupied by another particle. If there is more than one particle in a given region of space, then their sum is equal to the number of ..
Size of solute particles
Smaller the size of the particles greater is the solubility. For example, it is easier to dissolve powdered sugar than granules of sug..

Is electron really a particle or wave?
Upto the year 1924, electron was exclusively regarded as a particle. However, in 1924, de-Broglie suggested that an electron behaves both as a material particle and as a wave. Just like light, some experimental facts can be explained by assuming electrons as tiny particles..
The charge and mass of the positive particles
The e/m ratio of the anode rays obtained from hydrogen gas was found to be highest and equivalent to 9.58 x 10 4 C g - 1 . These particles carried a charge of 1.602 x 10 - 1 9 C. Thus, the mass of the positive particle from hydrogen gas is,..

Intensive investigation by scientists over the years led to the development of a mental model known as 'dynamic particle model..
Particle Nature of Light
According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surface. If we user a low intensity source,..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
Very good patient and encouraing than my school teacher. I would love to study with tutor vista rather than going to school.
Very informational yet simple and easy to comprehend. Tutor Vista is helping me a lot.
Extremely helpful, would love to have more session. Tutor gave me a clear understanding of what I needed help with the most. Great session.
