What else can I help you with?
When a substance is melting the temperature of the substance what?
it decreases.
Higher melting point than expected?
It is indeed possible for a substance to have a higher melting point than expected. This normally happens when the substance is impure.
What can infer about the attraction between particles in a substance with a low melting point?
The stronger the intermolecular forces, the higher the boiling point, because more kinetic energy is needed to break these intermolecular forces apart.
How can the melting point of water be changed?
by adding impurities the melting point of ice can be increased.... and perhaps can water melt i think the right question suppose to be how can the melting point of ice be changed?
When a substance changes from liquid to a solid it is called?
LIQUDIFCATION!!!!!!!! Change of phase; the process is called melting.
Is melting thermal energy or movement in particles?
Melting is when a substance changes from a solid to a liquid state due to an input of thermal energy that causes the particles to move more rapidly and break free from their fixed positions. It involves both the transfer of thermal energy and the increased movement of particles within the substance.
Is melting point classified as a chemical property or a physical property?
physical. melting does not change the substance; it only changes the state of matter (or the movement of particles).
What happens to particles in a substance whe the sustance's temperature increase?
When the temperature of a substance increases, the particles within the substance gain energy and move more quickly. This increased movement causes the particles to spread out and the substance to expand. Additionally, the increased kinetic energy may lead to changes in the substance's state, such as melting or vaporization.
When a substances particles absorb energy what happens to the motion particles?
When a substance's particles absorb energy, their kinetic energy increases, causing them to move more rapidly. This heightened movement can lead to a change in the state of the substance, such as melting from solid to liquid or boiling from liquid to gas. As the particles collide with one another more energetically, the overall temperature of the substance may rise.
What occurs to the particles in a substance at low temperature when energy is transferred to the substance as heat?
At low temperatures, the particles in a substance are in a relatively low-energy state and move slowly, often vibrating in place. When energy is transferred to the substance as heat, the particles absorb this energy, causing them to gain kinetic energy. As a result, their motion increases, leading to greater vibration or movement, which can ultimately result in a phase change, such as melting if the substance is solid.
Does melting increase or decrease?
When any object is melting, this indicate that the object is getting richer on energy. More energy mean more movement in particles on an atomic level. In other words, the movement increases.
Do elements melt?
I'm assuming you are talking about sub-atomic particles. The act of melting cannot be applied to particles because melting refers to a change of state of a substance. Substances, whether they be compounds or elemental, are a collection of atoms. These atoms, can be of 3 different states, depending on their temperature. If below the particular substance's melting point, it is solid. Between the melting and boiling point, the substance is liquid, and above the boiling point, the substance is gaseous. The state of the substance refers to the total amount of energy within the substance. Heat is energy, and melting a substance is only adding energy to it. the substance, on a molecular level, does not change when melting occurs. Therefore, melting a particle cannot occur, only energy can be added, which increases movement of the particles.
What are the changes in the kinetic energy as a substance is heated to its melting point?
As a substance is heated to its melting point, the kinetic energy of its particles increases, causing them to move more rapidly. This increase in kinetic energy leads to a rise in temperature until the substance reaches its melting point. At the melting point, the kinetic energy is used to overcome the forces holding the particles together, leading to the substance changing from a solid to a liquid state.
The temperature at which the particles of a substance have more kinetic energy to transform is?
The temperature at which the particles of a substance have enough kinetic energy to transform from one phase to another is called the phase transition temperature. This temperature varies depending on the substance and the phase transition, such as melting, boiling, or freezing.
What is the effect of heat on particles of matter?
Heat causes particles of matter to gain kinetic energy, leading to an increase in their vibration and movement. This increased movement allows particles to overcome intermolecular forces, leading to expansion of the substance and changes in its physical state (e.g. melting or boiling).
When are the terms melting point and freezing point used?
The term "melting point" is used to describe the temperature at which a substance changes from a solid to a liquid. The term "freezing point" is used to describe the temperature at which a substance changes from a liquid to a solid.
What change of state occurs when a substance reaches its melting point?
When a substance reaches its melting point, it changes from a solid to a liquid state. This is known as melting, where the thermal energy added causes the particles to overcome their fixed arrangement and transition into a more fluid state.
