What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
What type of substance can conduct electricity in the liquid but not solid phase?
Most ionic solids cannot conduct electricity in the solid phase. They only do so in the liquid phase. While they are solid, the ions in the ionic solid are fixed in their lattice so cannot move to conduct electricity whereas in the liquid phase, the ions are free and mobile and can act as charge carriers for electricity.
Non-solid metallic elements?
Metals can be solid or liquid. Through Melting Phase Transition, the solid metal will change its state from solid to liquid. Through Freezing Phase Transition, the liquid metal will change its state from liquid to solid.
Are most materials more or less dense in their solid state than in liquid?
Most materials are denser in their solid state than in their liquid state. This is because in the solid state, molecules are packed closely together in a fixed arrangement, while in the liquid state, they are more spread out and can move more freely.
What is the only element that cannot exist in a solid state?
Helium is the only element that cannot exist in a solid state under normal conditions. This is because helium has the lowest boiling point of all elements, at -268.9 degrees Celsius, which is close to absolute zero. At normal atmospheric pressure, helium transitions directly from a gas to a liquid state without forming a solid.
Is DNA in liquid state?
No DNA is in a solid state, only microscopic.
Is an electrolyte always liquid?
how does a liquid have a electrolyte in it and some dont
Why can't ionic compounds conduct electricity when they are in the solid state?
Ionic compounds cannot conduct electricity in the solid state because the ions are held in fixed positions within the crystal lattice and cannot move to carry an electric charge. Only when the ions are free to move in a liquid state or molten state can they conduct electricity.
What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
The state of the common elements on Mars?
The state of the common elements on Mars are all either a solid, liquid, or a gas. Some of them are found as only a solid, or only a liquid, or only a gas, or 2 of them, or all 3.
Do materials with ionic bonds conduct electricity in a solid and liquid state?
Materials with ionic bonds normally conduct electricity only in a liquid state. However metals, which have what are sometimes called "delocalized" ionic bonds, also conduct electricity in the solid state. It is now customary to consider metallic bonds a separate class from both ionic and covalent bonds.
What type of substance can conduct electricity in the liquid but not solid phase?
Most ionic solids cannot conduct electricity in the solid phase. They only do so in the liquid phase. While they are solid, the ions in the ionic solid are fixed in their lattice so cannot move to conduct electricity whereas in the liquid phase, the ions are free and mobile and can act as charge carriers for electricity.
Why does NaCl pass the current in liquid state only?
This is because in solution the NaCl dissociates into Na+ & Cl- ions which get attracted toward oppositely charged electrodes & thus completing the circuit . Hence, the current flows . This can't happen in solid state because in solid state there is lack of free ions & electrolyte {due to absence of water } & hence current can't pass.
Most non-metals are in what state?
Nonmetals can be solid, liquid or gaseous.
Is it melting when a change of state occurs when a gas cools?
When something goes from the vapor state to the liquid state it is called "condensing." Melting refers only to the transition from the solid to the liquid state.
Non-solid metallic elements?
Metals can be solid or liquid. Through Melting Phase Transition, the solid metal will change its state from solid to liquid. Through Freezing Phase Transition, the liquid metal will change its state from liquid to solid.
What state of matter keeps its shape?
Of the three states of matter...solid, liquid, or gas...only a solid wouldn't need a container.
