What else can I help you with?
When the particles ot the medium move back and forth along the direction of the wave motion the wave is a?
longitudinal wave
Who first came up with the idea of particles and what was his theory?
An ancient Greek, Democritus, hypothesized all things were made of atoms and that nothing could be smaller than atoms. Albert Einstein in 1905 demonstrated through mathematical theory that the motion of pollen particles in water (Brownian motion) was due to water molecules hitting against the pollen particles, which proved the atomic and molecular theory. This was confirmed experimentally in 1908. Also in 1905, Einstein explained the photoelectric effect (the emission of electrons from matter in consequence of absorption of energy from light) and concluded that light consisted of particles he called "photons". His Nobel Prize was awarded for explaining Brownian motion and proving the existence of atoms and molecules and for explaining the photoelectric effect in terms of particles of light. [He never received a Nobel Prize for his special or general theory of relativity].
What are the 4 kinetic molecular theory?
1. Gases 2.Particles in motion 3. 4. Particle Energy Sorry but these are the right ones just have not found number 3.
What is the significance of vis viva in the field of classical mechanics?
Vis viva, also known as kinetic energy, is significant in classical mechanics as it helps describe the motion and interactions of objects. It is a key concept in understanding how energy is transferred and conserved in physical systems, providing insights into the behavior of particles and systems in motion.
How do you prove the existence of an atom?
Using modern technology like scanning tunneling microscopy, pictures can be taken of atoms. Their existence has also been proven through Einstein's Brownian motion calculations, to mathematically estimate the distance tiny particles will move based on molecular bombardment. Another experiment was done using these calculations on particles of resin in water with positive results.
How does pressure affect a thermometer?
Heat is transferred thru the glass of the thermometer to or from the liquid (mercury) inside. The heat causes the liquid to either expand (hot) or contract. Since the large bulb end contains most of the liquid, but grass doesn't expand as much as the liquid, the expanding liquid forces itself up (if hot) into the narrow tube, which indicated the temperature. On the molecular level, particles outside the thermometer have a certain kinetic energy (KR) and the particles inside the thermometer also have a certain KE probably a different amount or they are already at the same temperature. Particles (either molecules or atoms) when in either the solid or liquid state, are constantly in motion (for solids, they just vibrate about a fixed, central position. Collision of the particles outside the thermometer and the thermometer itself cause exchange of some KE until the average KE of the outside particles is equal to the average KE of those in the thermometer. When this occurrs they are at the same temp. This change in KE of the particles in the thermometer causes more motion, and this extra motion causes what we call expansion. All molecules in the thermometer are pushing against each other with more force (KE).
What identifies how the particles of gases affect one another's motion?
they affect one another's motion only when they collide.
Which states identifies how the particles of gases affect one anothers motion?
The kinetic theory of gases identifies how gas particles affect each other's motion. It states that gas particles are in constant random motion, colliding with each other and the walls of their container. These collisions create pressure and affect the overall behavior of the gas.
Does a termomoter measures particle motion?
Yes, a thermometer measures the average kinetic energy of particles in a substance, which is related to their motion. As the particles move faster, the temperature increases, and as they move slower, the temperature decreases.
What statement identifies how the particles of gases affect one another's motion?
Gas particles are in constant random motion and move independently of each other, only interacting through collisions. These collisions can change the direction and speed of the particles, leading to changes in pressure and volume of the gas.
What happens to the motion of the particles?
The motion of particles can change due to various factors like temperature, pressure, and external forces. For example, at higher temperatures, particles tend to move faster, whereas at lower temperatures, their motion slows down. Additionally, external forces can affect the direction and speed of particle motion.
What weighs the motion of molecules?
thermometer. Temperature has to do with the average kinetic energy of molecules, and we find it with a thermometer
How do particles of gas affect one anothers motion?
Particles of gas affect each other's motion through collisions. When gas particles collide, they can transfer energy and momentum to each other, causing changes in speed and direction. These collisions influence the overall behavior of the gas, such as its pressure, temperature, and volume.
Which identifies how the particles of gases affect one anothers motion?
You think probable to the kinetic theory of gases.
How does the transfer of heat to an object affect the motion of the particles?
When heat is transferred to an object, the particles within the object gain kinetic energy, causing them to move faster and vibrate more vigorously. This increased motion of the particles leads to an increase in the object's temperature.
How can you describe the motion of the particles in a solid?
The particles are tightly packed so they vibrate.
What is the motion of particles?
Brownian motion
