The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.
Dissolving sugar in hot water is a chemical change.
Its physical because the chemical properities of it doesn't change.
they have a chemical change.Additional answerNo they don't, they have a physical change. Some things may decompose at their boiling point but that's nothing to do with melting or boiling, just being hot.
It is a physical change.
As you may know, determining whether a change is chemical or physical can sometimes be a real pain! This particular change is a hard one. If your talking about butter slightly melting on a hot day because it was left out on the counter, THAT is a physical change and is reversible by simply putting the butter into the fridge. However, melting butter on the stove and having it completely turn to liquid and turn a little brown, THAT is a chemical change and is hard to reverse... a chemical change has occurred while the butter was over the heat.
It is a physical property. A chemical property would involve the butter reacting to the toast, but the butter is actually reacting to the heat from the toast. The butter would melt against any surface hot enough, where as butter would not melt on cold toast. Hence, the reaction to heat makes it a physical property. (A relatively easy way to remember is that physical properties deal with the transfer of physical energy or force such as heat, inertia, etc. Chemical properties occur when two material substances trade molecules or electrons.)
It certainly is, unless you get it so hot it begins to char (then it becomes chemical).

Melting! Igneous rock is formed by melting, chemical and physical changes within the melt (magma) then solidifying.
Since it is the heat from the bread that causes the butter to change form (melt), and be absorbed by the bread, this should be classified as a chemical reaction.
a butter bar to a popcorn butterAn example of melting is an ice cube in the sun. Another example of melting is solid cooking grease like Crisco melting in a hot fry pan.
CHEMICAL:)
When you put butter over a hot pad, it becomes melted as in it became so hot that it could not stand it and it melted
Its a chemical reaction.

Dissolution is a physical change.
