Which scientist said that atoms are the smallest particle of an element that retains its chemical properties?
John Dalton, an English scientist, proposed the theory that atoms are the smallest particle of an element that retains its chemical properties. His work on atomic theory laid the foundation for modern chemistry.
How does the kinetic theory of matter explain insulation?
The kinetic theory of matter explains insulation by stating that heat transfer occurs through the vibration and movement of particles. Insulation materials, such as those with low thermal conductivity, work by reducing the movement of particles, limiting the transfer of heat energy. This creates a barrier that helps to maintain desired temperatures inside buildings or around systems.
Which theory did the work of virchow schwann and schleiden help to form?
cell theory
How did isaac newton work on light before electricity was invented?
Isaac Newton conducted experiments with light using prisms and observed how light could be separated into different colors through the process of refraction. He also proposed that light could be made up of particles rather than just waves. These experiments and ideas paved the way for the development of the wave-particle duality theory in modern physics.
What discovery resulted from the photoelectric effect?
The discovery resulting from the photoelectric effect was that light can behave as both a wave and a particle. This finding led to the development of the quantum theory of light, which laid the foundation for quantum mechanics.
What are the benefits of using particle board underlayment in flooring installations?
Particle board underlayment offers several benefits in flooring installations. It provides a smooth and stable surface for flooring materials to be installed on, helps to reduce noise and improve insulation, and is cost-effective compared to other types of underlayment materials. Additionally, particle board is easy to work with and can be easily cut to fit the dimensions of the room.

What did otto von guericke contribute to the particle theory?
Otto von Guericke contributed to the particle theory by conducting the famous Magdeburg hemispheres experiment which demonstrated the concept of a vacuum and the existence of air pressure. His work helped in understanding the nature of particles and their behavior in a vacuum.

Which subatomic particle did James chadwick discover?
James Chadwick discovered the neutron, a subatomic particle that is found in the nucleus of an atom. He made this discovery in 1932, building upon the work of previous scientists in the field of atomic theory.
How do you determine work done by electric field?
The work done by an electric field on a charged particle can be calculated using the formula: Work = charge of the particle x electric field strength x distance moved. The work is positive if the electric field and the displacement are in the same direction, and negative if they are in opposite directions.
How do linemen work on live wires?
Linemen work on live wires by using proper insulation gear, and by making sure that there is never any path for current to flow in case the insulation does fail. In some cases, the lineman can be raised to the potential of the line, but you still need the insulation, and you still need the technique of ensuring that no circuit can be accidentally created.
In which case does an electric field do positive work on a charged particle?
An electric field does positive work on a charged particle when the direction of the electric field is the same as the direction of the particle's movement.
What can be said about the speed of a particle if the net work done on it is zero?
If the net work done on a particle is zero, it means that the kinetic energy of the particle is not changing. Therefore, the speed of the particle remains constant.
Can plastic be used as insulation?
Plastic can be a lot of things, some will work well as insulation, some won't.
What is the formula for the work done by an electric field on a charged particle?
The formula for the work done by an electric field on a charged particle is given by W qEd, where W represents the work done, q is the charge of the particle, E is the electric field strength, and d is the distance the particle moves in the field.
Particle theory of matter say about?
The Particle Theory has 4 laws:1) All matter is composed of particles2) These particles have spaces between them3) These particles are always moving4) Particles are attracted to each otherThe theory is used to explain how every day things work. For example dissolving can be explained as the particles are simply rearranging themselves to fit between other particles.*Note the word theory in the title, it is there for a reason. This is purely hypothetical and has not been proven... yet.*Also particles have also been referred to as molecules.
