What else can I help you with?
What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
When are molecules of a substance in motion?
Molecules of a substance are in constant motion. Whether you have a solid, liquid, or gas, the particles are moving (but the speed and amount they move differs). Particles of a solid move the least (they basically vibrate), particles of a liquid can flow around one another, and particles of a gas have a lot of space between them because they move in random, constant motions.
When a substance changes from a solid to a gas what happens to the speed of the molecules?
When a substance changes from a solid to a gas, the speed of the molecules increases. In the gas phase, the molecules have more energy and move more freely compared to when they were in a solid state where they were tightly packed and vibrating in fixed positions.
What kind of cluster did our sun form in?
Our sun formed in a cluster known as a stellar nursery, which is a cloud of gas and dust where stars are born. The sun likely formed in a cluster with many other stars around the same time, but has since drifted away from its birth cluster.
What is the Jelly-like substance where other cell parts are located?
The jelly-like substance inside a cell where other cell parts are located is called cytoplasm. It provides structure and support to the cell and is the medium through which nutrients and molecules move around the cell.
How heating a substance affect that substance?
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
What is he freedom of movement in molecules in a substance called?
The kinetic theory of molecules gives the idea about the movement and the behavior of the molecules in any different phase. The chemical reactivity of a particular molecule can be identified on the basis of kinetic theory of molecules. The phase of molecules changes and so changes it entropy ( movement of molecule in available space)
What is the two ways of making evaporation happen faster?
To make evaporation happen faster, you can increase the temperature of the substance being evaporated, which provides more energy for the molecules to escape into the air. You can also increase air circulation around the substance to remove the evaporated molecules quickly, allowing more molecules to escape into the air.
What is the random molecular of a substance is greatest when the substance is?
In a gaseous state, as the molecules have the highest degree of freedom to move around and exhibit random motion. This leads to greater randomness in the distribution of molecular positions and velocities, resulting in a higher entropy compared to when the substance is in a liquid or solid state.
What is the name of the condition when the average velocity of atmospheric molecules around you is not zero?
The condition you are referring to is called temperature. Temperature is a measure of the average kinetic energy of the particles in a substance, such as air. When the average velocity of atmospheric molecules is not zero, it indicates that the substance has a non-zero temperature.
What number do these decimals cluster around?
78.638
What happens to the molecules of a substance when it is charring?
Normally, when substance burns, the molecules undergo a rapid oxidation, which excites the molecules greatly. The heat that is input into the substance, and the oxidation process, causes the molecules to move around very quickly. As the molecules return to their lower energy resting state, they shed the excess energy in the form of heat. When the goal is to char, instead of burn, the molecules are exposed to the same heat as for burning, but they are denied oxygen. Since the materials do not have access to oxygen, they do not burn (rapidly oxidize). All of the molecules still get excited, and move and bump into each other, but the fuel is not consumed, as that requires oxygen. Once the molecules of the substance get hot enough, any molecules of water or other liquids change state to a gas and are driven out of the substance being heated, because of the expansion of the gas. Charring is most commonly used to dry wood completely, without using up the wood's potential energy as fuel.
What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
How can a substance flow?
A substance can flow when its particles are able to move past one another. This typically occurs when the substance is in a liquid or gas state, allowing the particles to freely slide or flow around each other. Factors such as temperature, pressure, and molecular structure can influence how readily a substance can flow.
How do you replace the cluster on a Toyota Echo?
you pull out the fram around the cluster then there are 2 screws you unscrew them and unhook from the wiring harness
How do you remove a 2001 Mercedes Benz S430 instrument cluster?
Purchase or borrow the Mercedes cluster removal keys 9 bucks on eBay, and place them in the slots on the side of the cluster and pull the cluster straight out. Takes 2 minutes Get the cluster repaired in the USA for around $250
How does the hydrophobic effect contribute to changes in entropy within a system?
The hydrophobic effect increases entropy in a system by causing nonpolar molecules to cluster together in water, reducing the organization of water molecules around them. This leads to an increase in disorder and randomness, which is a key factor in the overall entropy change within the system.
