Scientists believe that the Earth's outer core, which is composed of liquid iron and nickel, stops S-waves (secondary waves) while allowing P-waves (primary waves) to pass through. S-waves, being shear waves, cannot travel through liquids, leading to a shadow zone where these waves are not detected. In contrast, P-waves, which are compressional waves, can travel through both solids and liquids, but they are slowed down when passing through the liquid outer core due to the change in density and state of matter. This difference in behavior helps scientists infer the composition and state of the Earth's interior.
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
When a solid changes to a liquid, it melts and gains more kinetic energy. When a liquid changes to a gas, it evaporates and gains even more kinetic energy. When a solid changes directly to a gas without passing through the liquid state, it is known as sublimation.
Cold weather slows down the process of chemical reactions, as low temperatures reduce the kinetic energy of molecules, making them move slower. This can impact various processes such as food spoilage, battery performance, and the rate of rust formation on metal objects.
Temperature is a measure of kinetic energy. Because liquid nitrogen is very cold, a system's kinetic energy will be collisionally transferred to the added liquid nitrogen. Thus, in general, adding liquid nitrogen will decrease a system's kinetic energy. (There are some exceptions where the system has less kinetic energy than the liquid nitrogen, such as liquid helium.)
No, the speed of light is fastest in a vacuum, where it travels at approximately 299,792 kilometers per second. In other mediums, such as liquids, the speed of light is slower due to interactions between the light and the atoms in the medium.
bicth do it look i know
i need help please!!!!!!!!!
The outer core is the part of the Earth that slows down or stops seismic waves due to the change in density and composition from the mantle. Seismic waves travel faster through solid materials like the mantle and crust, but slow down when they reach the liquid outer core.
It slows down an becomes distorted.
Condensation.
When a liquid is cooled, the rate of evaporation slows down
Freezing. The cold slows down the particles in the water and it becomes hard
Yes, the evaporation rate slows at lower temperatures.
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
Liquid morphine (roxinol) is used alot to help with pain and it slows down breathing
Factors that can affect the rate of speed of a liquid include temperature (higher temperature typically increases speed), viscosity (higher viscosity slows down the liquid), pressure (increased pressure can increase speed), and the presence of any obstacles or barriers in the liquid's path.
When molecules are allowed to cool, they lose energy and their movement slows down. This can lead to changes in their physical state, such as from a gas to a liquid or a liquid to a solid, depending on the specific molecules and conditions. Cooling can also affect the interactions between molecules, influencing chemical reactions and properties like solubility and viscosity.
