When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place explain?
When sugar is heated for a short time, it undergoes a physical change called caramelization. During this process, the sugar molecules break down and recombine into a new substance without changing the chemical composition of the sugar molecules. The result is the formation of a thick, colorless liquid substance known as caramel.
When sugar is heated a thick liquid substance is formed what change takes place?
When sugar is heated, it undergoes a chemical change called caramelization. Caramelization breaks down the sugar molecules, causing them to recombine and form a new compound that gives the sugar its characteristic brown color and rich flavor. The thick liquid substance that forms during caramelization is known as caramel.
Which substance if any showed no change when heated?
Water showed no change when heated at its boiling point. The temperature remains constant during the phase change from liquid to gas until all of the water has evaporated.
What type of substance is heated by radiation?
Any substance that absorbs the radiation is heated by it.
What will a graph show if the change in temperature of a substance is heated?
A graph of the change in temperature of a substance as it is heated will typically show an initial increase in temperature until a plateau is reached, known as the phase transition or melting point. After this, the temperature will continue to rise again as the substance transitions to a gas.
When sugar is heated for a short timea thick colorless liquid substance is formedwhat kind of change takes place?
A change in physical state occurs when sugar is heated and transforms into a thick, colorless liquid substance. This transformation from solid sugar to liquid form is a physical change, not a chemical change, as the chemical composition of the sugar remains the same.

Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
What is the name of the substance formed when iron is heated?
The substance formed when iron is heated in the presence of oxygen is called iron oxide, commonly known as rust.
Does the volume of an object change if heated?
The volume of a substance increases when heated
What is the product when sulphur is heated in oxygen?
When sulfur is heated in oxygen, the product formed is sulfur dioxide (SO2). This is a colorless gas with a sharp, pungent odor.
What is the colour of chloroform when heated?
Chloroform is a colorless liquid at room temperature. When heated, it may turn to a colorless gas.
What is a physical change rather than a chemical change?
`A physical change is one in which matter is changed into another physical state without changing its chemical constitution(eg-ice melts to water,in both case substance is H2O).A chemical change is where there is a chemical change of the substance during the process(eg-CaCO3 is heated to form CO2 and CaO,here the new substance formed is unrelated chemically to parent substance.)
How can volume change if a substance undergoes a chemical change?
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
When a substance is heated its temperature increases. What other change might be observed?
Ordinarily when a substance is heated it expands. In some cases it melts. In some cases it vaporizes/evaporates.
A graph that shows the change in the temperature of a substance as it is heated will show?
A graph showing the change in temperature of a substance as it is heated will typically show an initial increase in temperature as heat is added, followed by a plateau where the substance changes phase (e.g., from solid to liquid), and then another increase in temperature. The specific shape of the graph will depend on the properties of the substance being heated.
When zinc and copper are heated brass forms. what kind of change is this?
When zinc and copper are heated together brass is formed, most people would think that this is a chemical change. But this is a common misconception. Brass is an alloy, a mixture of metals. There aren't brass molecules. This is a physical change because no new substance is formed, the copper and zinc just mix around.
