What happens to the amount of surface area of a particle compared to its mass as its size gets smaller?
As a particle's size gets smaller, its surface area-to-mass ratio increases. This is because as the particle shrinks, its volume (and therefore mass) decreases faster than its surface area. This increased surface area-to-mass ratio can influence the particle's reactivity, solubility, and other properties.
Which has the smallest mass?
Hydrogen has the smallest atomic mass at roughly 1.008 grams per mol (6.02x10^23 atoms)
What happens to capillarity as particle size increases?
As particle size increases, capillarity decreases because larger particles have lower surface area-to-volume ratio, reducing the ability to draw in and hold water through capillary action. This is because larger particles have less surface area available for water to cling to compared to smaller particles.
Consider a weathered rock or soil particle lying on a slope How will the gravitational force pulling the particle downward along the land surface vary with the inclination of the slope?
The gravitational force pulling the rock or soil particle downward along the land surface will increase with the inclination of the slope. Steeper slopes have a greater component of gravitational force acting parallel to the slope, causing the particle to move more easily downhill compared to shallow slopes.
What is the effect of particle size on angle of repose?
As Particle size increases the angle is repose decrease. Reason being, smaller particles have dominant cohesive and adhesive forces as compared to particle weight whereas in bigger particles gravity plays a dominant role so less repose angle.

What will be the relative velocity and momentum of a particle?
Without access to the particle and the system to which it is being compared it is impossible to say.
How are spherical nodes utilized in the field of physics to study particle interactions?
Spherical nodes are used in physics to represent the positions where particles interact with each other. By studying the interactions at these nodes, scientists can better understand the behavior and properties of particles.
What is the charge of alphaparticle as compared to proton?
The charge of an alpha particle is twice that of a proton.
If the velocity of a particle is nonzero can the particle's acceleration be zero?
yes. If the forces acting on the a moving particle are in equilibrium, (e.g. when a spherical object reaches terminal velocity (neglecting increased air resistance as it gets closer to the ground)) then the particle will be moving at a velocity, that is not 0, yet the velocity will remain constant, and the body will not accelerate or decelerate in any direction, and thus the acceleration is 0.
What is the derivation of Stokes' Law?
Stokes' Law is derived from the balance of forces acting on a small spherical particle moving through a viscous fluid at low Reynolds numbers. The law describes the drag force experienced by the particle as it moves through the fluid.
What is the expression for the l2 operator in spherical coordinates and how does it affect the quantum state of a particle in a spherically symmetric potential?
The expression for the (l2) operator in spherical coordinates is ( -hbar2 left( frac1sintheta fracpartialpartialtheta left( sintheta fracpartialpartialtheta right) frac1sin2theta fracpartial2partialphi2 right) ). This operator measures the square of the angular momentum of a particle in a spherically symmetric potential. It quantifies the total angular momentum of the particle and its projection along a specific axis. The eigenvalues of the (l2) operator correspond to the possible values of the total angular momentum quantum number (l), which in turn affects the quantum state of the particle in the potential.
What Different particle shapes?
Different particle shapes include spherical, cubic, cylindrical, and irregular geometries. Spherical particles are often found in powders and aerosols, while cubic particles are common in crystalline materials. Cylindrical shapes can be seen in fibers and rods, and irregular shapes are typically found in natural materials and some manufactured substances. The shape of particles significantly influences their physical properties, flow behavior, and interactions in various applications.
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
Which particle is bigger Ca or Ca2 plus?
The particle Ca2+ is bigger in size compared to the Ca particle. This is because Ca2+ has an additional charge compared to Ca, which results in a larger ionic radius due to increased electron-electron repulsion that can overcome the attractive force between the nucleus and electrons.
If an particle hits a gold nucleus in a head on collision the particle will not be deflected very much?
Correct, due to the massive size of the gold nucleus compared to the size of the incoming particle, the particle will not experience a large deflection in a head-on collision. This is because of the concentrated positive charge in a small space in the gold nucleus that causes a very strong Coulomb repulsion when the incoming particle gets close to it.
The area of particle 1 is 2.5 mm square The area of particle 2 is 0.5 mm square The area of particle 1 is how many times as big as the area of particle 2?
