During cooking, grains undergo physical changes like absorbing water and swelling, leading to softer texture and increased volume. Chemically, starches in grains break down into simpler sugars, proteins denature and coagulate, and some vitamins and minerals may leach out into the cooking water.

Can new compounds form during a physical change?
No, physical changes involve the rearrangement of atoms or molecules without altering their chemical composition. New compounds are not formed during physical changes.
Is seeds to pumpkin physical or chemical change?
This process involve chemical reactions but also physical changes.
Is baking a cake physical or chemical changes?
Baking a cake involves both physical and chemical changes. The physical changes include mixing the ingredients, changing the shape and texture of the batter, and the evaporation of water during baking. The chemical changes occur when the heat causes the baking powder to react, creating bubbles that make the cake rise, and when proteins and starches denature and coagulate during baking.
How do the particles that make up matter compare during physical and chemical changes?
During physical changes, the particles that make up matter remain the same and only their arrangement or state changes. In contrast, during chemical changes, the particles undergo a rearrangement or bonding at the atomic level, resulting in the formation of new substances with different properties.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Is making jam chemical or physical changes?
Making jam involves both chemical and physical changes. Chemical changes occur when the fruit's natural sugars break down during cooking, leading to caramelization and the creation of new complex flavors. Physical changes occur when the mixture thickens as pectin molecules form a gel-like structure to give the jam its characteristic texture.
Is cooking a turkey a chemical or physical change?
Cooking a turkey is a chemical change because the heat causes the proteins in the turkey to denature, which changes its chemical composition. The Maillard reaction that occurs during cooking also results in the formation of new compounds, altering the chemical properties of the turkey.
Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
Can new compounds form during a physical change?
No, physical changes involve the rearrangement of atoms or molecules without altering their chemical composition. New compounds are not formed during physical changes.
How can you tell if a physical reaction is occuring?
During a physical change the chemical molecule is not affected; physical changes are changes of phase or form.
What property stays the same during physical or chemical changes?
The mass.
What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
Are sugar from wax created by bees are chemical or physical change?
The process of bees converting nectar into beeswax and then into honey involves both chemical and physical changes. Chemical changes occur during the conversion of nectar into beeswax and honey, while physical changes occur during the shaping, cooling, and solidification of the wax.
Is seeds to pumpkin physical or chemical change?
This process involve chemical reactions but also physical changes.
Is Brewing beer a physical or chemical change?
Brewing beer involves both physical and chemical changes. Physical changes include crushing grains and boiling water, while chemical changes occur during fermentation when yeast converts sugars to alcohol and carbon dioxide.
What changes occur to raw materials during the paper making process?
During the paper making process, raw materials such as wood pulp or recycled paper undergo various changes. These include breaking down the fibers, removing impurities through a cleaning process, mixing with water to form a slurry, and pressing and drying the slurry to form thin sheets of paper. The end result is a cohesive material that can be used for writing, printing, or packaging.
Is baking a cake physical or chemical changes?
Baking a cake involves both physical and chemical changes. The physical changes include mixing the ingredients, changing the shape and texture of the batter, and the evaporation of water during baking. The chemical changes occur when the heat causes the baking powder to react, creating bubbles that make the cake rise, and when proteins and starches denature and coagulate during baking.
