Substances can change shape when heated due to the increase in kinetic energy of their particles. As temperature rises, particles move more vigorously, causing them to overcome intermolecular forces and allowing the substance to become more malleable or fluid. In solids, this can lead to melting, while in liquids and gases, it can result in expansion. This property is crucial in processes like molding and shaping materials in various industries.

Where physical properties are change in particular objects of matter?
Physical properties of matter can change through processes like heating, cooling, compression, or interaction with other substances. These changes can result in alterations to properties such as color, size, shape, density, or state of matter (solid, liquid, gas). Examples include ice melting into water when heated, or metal expanding when heated.
Do enzymes change shape to move substances across the plasma membrane?
Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.
Which one is not a sign of a chemical change change in shape bubbling smoking changing color?
Changing shape is not typically a sign of a chemical change. Chemical changes involve the rearrangement of atoms and molecules to form new substances with different properties. Shape change is more likely a physical change.
What do substances do when heated because of the molecules?
they expand
Most substances change their physical state and?
Most substances change their physical state and transition from solid, to liquid, to gas when heated or cooled. This phase transition occurs due to changes in the arrangement and movement of the particles within the substance.
Are all substances the same before and after burning?
No, some substances change their whole form and others just change their color and shape.
What are phosphorescent pigments?
it is a solidifid piese of meatle that can change its shape when re heated
What expands when its heated?
Most substances expand when heated.

Why do metallic substances change shape when struck?
Malleability is a property of all metals.
What do Metals and other substances do when heated?
materials usually expand when heated.
What evidences a physical change?
"A physical change occurs when some of the properties of a material change, but the substances in the material remain the same." "...any actions that change the size and shape of a material, but not its composition." if the shape/form is changed but not its makeup, then that change is physical
Do enzymes change shape to move substances across the plasma membrane?
Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.
What happens to substances when they are heated?
When substances are heated, their molecules gain energy and move more rapidly. This increase in molecular motion can cause substances to change state (e.g. from solid to liquid), react with other substances, or decompose into simpler chemical components. Ultimately, heating a substance can lead to a variety of physical and chemical changes depending on the specific properties of the substance.
Is making nugget a physical or chemical change?
As long as you are not adding or subtracting substances, the shape you put the metal in is purely a physical change.
