What else can I help you with?
Why would a substance dissolving in one solvent but not in another?
A substance may dissolve in one solvent but not in another due to differences in polarity, intermolecular forces, or chemical interactions between the solute and solvent molecules. The solute must be compatible with the solvent at a molecular level in order for dissolution to occur.
A chemical change in which a substance becomes more negative?
The chemical change in which a substance becomes more negative could be the ionization of the substance. Means that the substance becomes more negatively charged and that is due to it being ionized. It tends to gain more electrons in order to fill its valence shell to become a stable substance.
What must be present in order for asubstance to changev from one state of matter to another?
For a substance to change from one state of matter to another, energy must be added or removed to break or form intermolecular forces. The temperature and pressure conditions must also be appropriate for the desired state change to occur, such as melting, boiling, or freezing.
Can you get marijuana in your system from touching it?
No, marijuana cannot enter your system simply from touching it. It needs to be ingested, smoked, or vaporized in order to be absorbed into the body. Touching marijuana will not result in intoxication or the presence of THC in your system.
Which shows the temperatures of three substances in order from greatest to least?
Substance A: 100°C, Substance B: 98°C, Substance C: 90°C
Why must substances be touching in order from conduction to occur?
Conduction is the transfer of heat between substances due to direct contact. When substances are touching, their particles can transfer kinetic energy (heat) by colliding with each other, causing the heat to flow from the warmer substance to the cooler one. Without direct contact, there is no medium for the transfer of heat energy to occur.
In order for heat to be transferred by conduction which of the following must occur A cold object must be heated with hot air. A hot object must be directly touching a cold object. The Sun must heat t?
A hot object must be directly touching a cold object for heat to be transferred by conduction. Conduction is the process of heat transfer through direct contact between particles of a substance. Heat flows from the hotter object to the colder object until thermal equilibrium is reached.
Why must substances be touching in order for conduction occur?
Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
In order for conduct to occur two objects must occur?
Two objects must be touching and it has to transfer heat
In order for heat to be transferred between two objects by conduction?
the objects must be in physical contact with each other, and there must be a temperature difference between them. Heat will flow from the object with a higher temperature to the one with a lower temperature until thermal equilibrium is reached.
Describe heat transfer by conduction?
2 objects must be touching each other in order to transfer heat.
What must occur in order to form a solution?
The correct answer is as follows: One Substance Must Dissolve In Another.
Do two things neeed to be touching in order to transfer charge?
No, two things do not need to be touching in order to transfer charge. Charge can be transferred between objects through processes such as induction or conduction, where the charge is either redistributed or passed from one object to another without direct contact.
What is needed in order for conduction to happen?
Conduction requires a medium, such as a solid, liquid, or gas, through which heat can be transferred. The temperature difference between two objects is also needed for conduction to occur, as heat naturally flows from a warmer object to a cooler one through direct contact. Additionally, materials with higher thermal conductivity allow heat to transfer more efficiently through conduction.
Which method of heat transfer is it necessary for the objects to be touching one another?
Conduction is the method of heat transfer that requires objects to be in direct contact with each other in order to transfer heat. It occurs through the collision of particles in a solid material.
Why is it not possible to electrolyse a solid substance?
It is not possible to electrolyze a solid substance because in order for electrolysis to occur, the substance needs to be dissolved in a liquid or molten form to allow for the movement of ions. Solids do not allow for this movement of ions required for electrolysis to take place.
Can a chemical reaction occur without any new substanced?
No, in order for a chemical reaction to take place, a new chemical substance must be formed.
