Does boiling point and melting point occur at the same temperature?
It depends on the substance and the pressure. For most substances at atmospheric pressure, the boiling point is much higher than the melting point. However, some things, like nitrogen and carbon dioxide, do not have any liquid phase at atmospheric pressure--they go directly from solid to gas and vice-versa.
What can occur when matter changes state?
when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
Is the boiling point of a substance a physicsl property?
No, the boiling point is a physical property because the compound or substance is not changing chemically (only physically from a liquid to a gas). The boiling point is considered the temperature at which the vapor pressure of the liquid equals the atmospheric pressure surrounding the liquid. All of these are physical properties, making the boiling point a physical property too.
What does changes of state in science matter mean?
In science, changes of state refer to the physical changes that occur when a substance transitions from one state of matter to another, such as from solid to liquid or from liquid to gas. Understanding these changes is important because they help explain properties and behaviors of different materials under various conditions. Studying changes of state also helps scientists develop new materials and technologies.
What is saturated heat?
Saturated heat refers to the amount of heat required to convert a substance from a solid to a liquid or from a liquid to a gas at its boiling or melting point, while keeping the temperature constant. It represents the energy needed for a phase change to occur without changing the temperature of the substance.
What are 5 physical changes that can occur to a substance?
Melting: The substance changes from a solid to a liquid as heat is applied. Freezing: The substance changes from a liquid to a solid as it loses heat. Evaporation: The substance changes from a liquid to a gas as it is heated. Condensation: The substance changes from a gas to a liquid as it cools. Sublimation: The substance changes directly from a solid to a gas without going through a liquid phase.
Does melting occur when a solid changes to a liquid?
yes
What are the Changes of state?
There are three main states that a substance can exist as: solid, liquid and gas. The transition between these states occur when a substance is heated or cooled past their freezing/melting or boiling/condensing points. Solid -> Liquid = Melting Liquid -> Gas = Boiling Gas -> Liquid = Condensing Liquid -> Solid = Freezing
Does boiling point and melting point occur at the same temperature?
It depends on the substance and the pressure. For most substances at atmospheric pressure, the boiling point is much higher than the melting point. However, some things, like nitrogen and carbon dioxide, do not have any liquid phase at atmospheric pressure--they go directly from solid to gas and vice-versa.
Can the temperature at which a substance melts is the same temperature at which it changes from liquid to solid?
Yes. Melting point is changing from a solid to liquid & freezing point is changing from a liquid to a solid. Both occur at the same temperature & these terms are usually used interchangably, although melting point is probably used more often than freezing point.
Is the melting and boiling point physical?
The melting and boiling points of a material are physical properties of that material.Melting is a solid becoming a liquid, and boiling is a liquid becoming a gas. These are changes between the three different phases a substance can be in (solid, liquid, and gas*). Both of these changes can occur through the application of varying amounts of heat** . All substances can go through these stages. When a substance changes stages, they remain the same substance, so the change is a physical change.*a fourth, controversial stage is plasma, which is an electrically charged substance.**A liquid can also become a gas by extreme low pressure.
When melting occur and what is it called?
Melting occur at the melting point. The solid is transformed in a liquid.
When does the melting point occur?
Melting occur when a solid starts to be a liquid.
When does phase changes occur?
When a solid melts or changes to a liquid. When a liquid boils or changes to a gas. or the reverse when a gas condenses to a liquid or a liquid freezes to a solid. Also it is possible for a solid to go directly to a gas without passing through the liquid stage. This is called sublimation and can occur with sulfur when heated, or ice in the winter when the sun shines on it..
What are the phase changes of matter?
The phase changes of matter are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). These transitions occur due to changes in temperature and pressure.
What are the similarities for freezing and melting?
Both freezing and melting involve a change in the state of matter from solid to liquid or liquid to solid, respectively. The temperature at which freezing and melting occur is the same for a given substance, known as the freezing/melting point. During both processes, energy in the form of heat is either released (freezing) or absorbed (melting).
What can occur when matter changes state?
when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
