Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
The only example of a chemical change in the list is iron rusting. The other three are all examples of physical changes.
Is water freezing to form a ice a chemical change?
No, freezing is not a chemical change. It is a physical one. It (freezing) is reversable, and the substance that is changing state to a solid or from a solid is not undergoing any chemical changes.
3 examples of physical changes?
Because there are currently four known states of matter, one change between each of these states yields three different types of state change. One is the change from a solid to a liquid, which we will call "melting." The second is the change from a liquid to a gas, which we call "vaporization." The third is the change from a gas to a plasma. There are terms for these changes in the reverse direction, and sublimation describes the change from a solid to a gas with no intermediate liquid phase.
Is drying leaves a chemical change or a physical change?
Drying of leaves is a physical change because neither it changes its composition nor does it have any different properties from the original one.
Is gasoline evaporating a chemical or physical change?
Physical change if I am correct.It will be a different form than the original.In your basic science classes you learned that if you for ex. have water as a solid,liquid and gas they are all the same thing because if solid ice=ice melts that means water,that if it is a liquid it is in its original state and that if it is a gas then it evaporates.The change is physical due to the appearance of it and the form it takes just changing.If a chemical reaction were to take place you would feel heat,sparks,etc.Hope this helps.
Is pouring three liquids into a single container form distinct layers an examples of a chemical change?
No. It is a physical change. The layers occur because the three liquids have different densities. There is no chemical change taking place.
Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
The only example of a chemical change in the list is iron rusting. The other three are all examples of physical changes.
What are three differences between physical and chemical changes?
(i) Physical change does not result in formation of new substances Chemical change result in formation of new substances (ii) Physical change is a temporary change Chemical change is a permanent change (iii) Physical change is reversible Chemical change cannot be reversed back (iv) e.g of Physical change-Dissolving of sugar in water to obtain a sugar solution e.g of Chemical change-Burning of sodium in chloride
What are the three main causes of weathering?
Physical, chemical and biological change are the three main causes of weathering.
Is water freezing chemical change?
No, it is a physical change. You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
what Three examples of physical changes are?
A physical change is any sort of change in an object's physical appearance or physical state of being.Some examples of physical changes include:freezing a glass of watercutting wooddropping plates, or cupschopping fruits or vegetablestearing paperbreaking itemschewing pencilspeeling potatoes
If the melting of water is physical or chemical change?
physical Water cannot melt because it is a liquid. However, a snowflake or an icicle can melt because they are solid states of water. You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
Three physical changes and three chemicl changes?
Three clues of chemical change : a gas , light, solid, color. JoJo
Is water freezing to form a ice a chemical change?
No, freezing is not a chemical change. It is a physical one. It (freezing) is reversable, and the substance that is changing state to a solid or from a solid is not undergoing any chemical changes.
Is evaporating water a physical change or a chemical change?
When water evaporates, it is a physical change.You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
Is liquid water freezing to form ice a chemical change?
No. It is a physical change. You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
Is water freezing in a puddel an chemical change?
no, physical You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ). Changing physical states is not a chemical change, but a direct result of heat or cold application.
