True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
When a substance change from one physical form to another you say the substance has had an?
When a substance changes from one physical form to another, it has undergone a phase change. This can include processes like melting, freezing, vaporization, condensation, and sublimation.
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.
Does melting occur when a substance changes from a liquid to a solid?
No, melting occurs when a substance changes from a solid to a liquid through the absorption of heat energy. When a substance changes from a liquid to a solid, it is referred to as freezing.
What are the four main phase changes and how does heat affect their change?
The four main phase changes are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), and condensation (gas to liquid). Heat is needed to overcome intermolecular forces between particles during melting and vaporization, causing the substance to change phase. On the other hand, heat is released when particles come together and form intermolecular forces during freezing and condensation.
What are the phase changes?
Melting, Freezing, Condensation, Evaporation, and Sublimation.
What are the 5 changes of state?
sublimation melting freezing condensation vaporation
What is a list of the 5 changes of state?
boiling sublimation freezing melting condensation
What are the six different phase changes?
The six different phase changes are: Melting (solid to liquid) Freezing (liquid to solid) Vaporization (liquid to gas) Condensation (gas to liquid) Sublimation (solid to gas) Deposition (gas to solid)
Are the melting and freezing of a substance the same?
Yes. A substance melts and freezes at the same temperature. Melting is as it changes from solid to liquid, freezing is from liquid to solid.
Is a condensation point the same as a melting point?
No, a condensation point is the temperature at which a substance changes from a gas to a liquid, while a melting point is the temperature at which a solid changes to a liquid.
Which state changes are exothermic and endothermic?
Exothermic state changes release heat energy to the surroundings, such as freezing and condensation. Endothermic state changes absorb heat energy from the surroundings, like melting and vaporization.
True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
Which of the following is a change of state of a substance?
solid to gas,solid to liquid,liquid to gasare endothermicthe reverse are exothermicSource: http://answers.yahoo.com/question/index?qid=20081022202228AAFplBc
Melting freezing and boiling are what kind of change?
Melting, freezing, and boiling are physical changes, as they do not involve a change in the chemical composition of the substance.
When a substance change from one physical form to another you say the substance has had an?
When a substance changes from one physical form to another, it has undergone a phase change. This can include processes like melting, freezing, vaporization, condensation, and sublimation.
The melting point of a substance is its freezing point.?
No, the melting point of a substance is the temperature at which it changes from a solid to a liquid, whereas the freezing point is the temperature at which it changes from a liquid to a solid. These points are usually the same for a pure substance under normal atmospheric pressure.
