What else can I help you with?
What is happening when your body changes the food you eat into energy you need to grow A. a chemical change B. a physical change C. a chemical property D. a physical property?
When your body changes the food you eat into energy, it involves a chemical change (A). This process, known as metabolism, includes breaking down food molecules through chemical reactions to release energy, which is essential for growth and maintaining bodily functions.
Is custard being made a physical or chemical change?
The process of making custard involves both physical and chemical changes. physical changes include mixing ingredients together and heating them, while chemical changes occur when the proteins in the eggs denature and coagulate to form the custard's texture.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Changes of state are considered physical changes because?
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
What changes are happening when a fire burns in a fireplace?
A physical and Chemical change.
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.

What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.

Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
Changes in properties of matter are called?
physical or chemical changes
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
When carbon dioxide in air converts to more complex molecules by plants during photosynthesis is that a physical change?
No, the process of carbon dioxide being converted into more complex molecules by plants during photosynthesis is a chemical change, not a physical change. Chemical changes involve the formation of new substances with different chemical properties, whereas physical changes only affect the physical state of a substance without altering its chemical composition.
Is dissolving NaCl in h2o a chemical change?
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
How you describe the changes that happened to the materials when heated?
When materials are heated, they can undergo physical or chemical changes. Physical changes include state changes like melting or boiling, while chemical changes involve the molecules rearranging to form new substances. Heating can also increase the kinetic energy of molecules, causing them to move faster and potentially break bonds.
