Can an astronaut hear a mile away when helmet mic is broke?
Because sound needs particles to travel through ; when a sound from inside one helmet is made, the particles vibrate the surrounding particles therefore vibrating the other astronauts helmet particles ( as they are touching) allowing him to hear the sound.
Why decanting is not a good way of separation?
Decanting is not always an effective method of separation because it relies on the difference in density between liquids or solids, which may not be significant enough for clear separation. Additionally, decanting can leave behind impurities or small particles that remain suspended in the liquid. Furthermore, it is not suitable for separating homogeneous mixtures, where the components are uniformly distributed. Overall, while decanting can work for certain scenarios, it is often less precise than other separation techniques like filtration or centrifugation.
Some regions along the plane of the Milky Way appear dark because?
stars in that region are hidden by dark dust particles.
Why do you sneeze if there are ashes?
Because some of the ash particles get in your nose, and irritate the nerves in your nose, that's the bodies way of getting stuff out of your nose.
How is the relationship between protons and alpha particles similar to the relationship between beta particles and electrons?
An Alpha Particle is a fast, bare Helium nuclei composed of two protons, two neutrons, and no electrons, that is ejected at high velocity from a decaying nuclei. A Beta Particle is an electron or positron, ejected at extremely high velocity from a decaying nuclei. Both alpha particles and protons are Bosons. Both beta particles and electrons are Leptons. Their relationships are similar because the electron and proton are both components of atoms. The beta and alpha particles are both fragments ejected from decaying atoms.
Is a saline a heterogeneous mixture?
yes
Is wet sand heterogenous or homogenous?
Wet sand is considered heterogeneous because it contains a mixture of different-sized particles that are not uniformly distributed.
Is an iron fillings and sand a solution suspension or colloid?
An iron filings and sand mixture is a suspension because the particles are large enough to settle out over time due to gravity. In a solution, the particles are uniformly distributed and do not settle.
Why do solutes dissolve?
Solutes dissolve in solvents due to intermolecular forces between solute and solvent particles. These forces break the bonds holding solute particles together, allowing them to disperse uniformly in the solvent. This process forms a homogenous mixture known as a solution.
Is a colloid a homogenous mixture?
A colloid is actually a heterogeneous mixture. HETEROGENEOUS MIXTURE- Heterogeneous mixture means the mixture in which the particles are not uniformly mixed with each other. In a colloid the particles are very very minute and so are not visible to our eyes. For example milk is colloid. So according to me colloid mixture appears to be a homogeneous mixture but actually it is a heterogeneous mixture.
Why is water and gravel a suspension?
Yes because you can still see the gravel inside the water
Why urea solution is not a colloid?
Urea solution is not a colloid because it is a homogeneous mixture where the urea molecules are uniformly dissolved in the solvent, usually water. In a colloid, the particles are not dissolved but are suspended within the solvent, resulting in a heterogeneous mixture.
Is glucose solution a homogenous mixture?
Yes, a glucose solution is a homogeneous mixture because glucose particles are uniformly distributed throughout the solvent, usually water. This means that the composition and properties of the solution are the same throughout.
The ability to become uniformly distributed describes what type of matter?
The ability to become uniformly distributed describes matter in the gaseous state. Gases have the ability to fill the container they are in completely and evenly, spreading out to fill all available space. This property is a result of the high kinetic energy and weak intermolecular forces present in gases, allowing them to move freely and disperse throughout their container.
Why does gas fill the container?
Gas fills the container because gas particles are in constant, random motion and will spread out to uniformly fill the space available to them. This behavior is governed by the gas particles colliding with each other and the walls of their container, creating pressure that pushes the gas to expand until it reaches equilibrium.
Is Iodine and water a heterogeneous or homogeneous mixture?
A heterogeneous mixture is a mixture of two or more substances that are not uniformly distributed. The iodine and water in the question are not homogeneous because they are not uniformly distributed.
Is unfiltered air homogeneous or heterogeneous?
Unfiltered air is heterogeneous because it is composed of a mixture of different gases, particles, and possibly microorganisms. This means that the components are not uniformly distributed throughout the air.
