What Explain what happens to the average kinetic energy, thermal energy, and temperature of a substance when the particles in the substance slow down.?
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.
How can you explain crystallizing using the particle theory?
When a solid (the solute) dissolves in a liquid (the solvent) the resulting mixture is called a solution. If the solvent is evaporated, then the solid is reformed or crystallized because, as the liquid particles are removed, the solid particles become closer and closer together and eventually bond into a solid.
In a desert soil containing a mixture of sand and small rocks is exposed to wind erosion. Over time how would the land surface change Explain.?
As the wind blows over the desert soil, it will pick up loose particles of sand and small rocks, causing erosion. Over time, the land surface will become more eroded and flattened, with the removal of smaller particles leaving behind larger rocks and creating a more barren landscape. This process can lead to the formation of sand dunes and bare rock surfaces as the finer particles are carried away by the wind.
Explain how density affects porosity?
Increasing density decreases porosity, as the material becomes more compact and there is less space between particles for fluids to flow through. Conversely, decreasing density increases porosity, allowing for more pore space within the material.
Name four clastic sedimentary rocks and explain how these rocks form?
Sandstone: formed by the cementation of sand grains. Conglomerate: formed by the cementation of rounded pebbles. Siltstone: formed by the compaction of silt-sized particles. Shale: formed by the compaction of clay and silt particles.
Are virtual particles real, or are they simply theoretical constructs used to explain certain phenomena in quantum mechanics?
Virtual particles are theoretical constructs used in quantum mechanics to explain certain phenomena, but they are not considered to be real particles in the traditional sense.
Explain how solids are terms in particles?
In a solid, the particles are tightly packed and do not move around much, as opposed to a liquid or gas, in which the particles are more spread out.
Explain why the volume of a gas can change?
because the particles are away from each other so, the particles are spreading in an object
How does the design of gas particles explain why gases have no definite volume?
the gas
Which group commonly combines with group 1 elements explain why?
These are elements from the group 17 - halogens; a strong electrostatic attraction exist beween atoms.
What theory is used to explain the behavior of particles in matter?
kinetic theory
How does the movement of particles in a liquid help explain the shape and volume of liquids?
They dont
How does a particle theory explain how a solute dissolves into a solvent?
You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.
Explain why sound travels quickest through a solid?
This is due to the particles and the density of the the object
Explain the difference in the motion of particles for each state of matter?
blahh blahh blahh
What theory did brown suggest to explain the nature of heat?
Brown suggested the kinetic theory of heat to explain the nature of heat. This theory proposes that heat is the result of the movement of particles in a substance, and that as particles move faster, the substance's temperature increases.
How did Rutherford explain the fact that some of the alpha particles bounced sharply back off the gold foil?
Rutherford explained the sharp bounce of some alpha particles off the gold foil by proposing that atoms have a dense, positively charged nucleus at their center. Most of the alpha particles passed through the foil because the majority of an atom is empty space, but those that were deflected at large angles encountered this concentrated mass of positive charge, which repelled the alpha particles due to electrostatic forces. This led him to conclude that the atom's structure is mostly empty space with a small, dense nucleus, fundamentally changing the understanding of atomic structure.
