The liver, pancreas, and small intestine are involved in the chemical and physical changes of fat in the body. The liver produces bile, which helps break down fat globules into smaller droplets. The pancreas releases enzymes that further break down the fats into absorbable molecules in the small intestine.

Is adding magnesium and heat chemical or physical change?
Heating magnesium is a physical process.But the reaction of magnesium with oxygen at high temperature is a chemical process.
Is mending a broken bone a physical change?
Healing a broken bone involves a combination of physical and chemical changes. The bone undergoes physical changes as it reconnects and reforms its structure, while chemical processes occur to help repair and strengthen the bone tissue.
What are some steps to physical and chemical change?
Physical change involves a change in the form or state of matter without changing its chemical composition, such as melting ice to water. Chemical change involves a change in the chemical composition of a substance, resulting in new products being formed, such as burning wood to produce ash and smoke. Observing changes in properties, such as color, odor, or temperature, can help distinguish between physical and chemical changes.
What question could you ask to help you decide whether silver underwent a chemical change or physical change?

What methods do scientist use to determine if it is a physical or chemical change?
Scientists distinguish between physical and chemical changes by examining if the change affects the chemical composition of the substances involved. Physical changes alter the appearance or state of a substance without changing its chemical makeup, while chemical changes result in the formation of new substances with different chemical properties through chemical reactions. Techniques such as observing color changes, production of gas, formation of a precipitate, or changes in temperature can help scientists identify whether a physical or chemical change has occurred.

Is oil and water being shaken together to make salad dressing a chemical change?
No, shaking oil and water together to make salad dressing is a physical change. The oil and water still retain their individual chemical properties and can be separated easily.
How can a thermometer be used to help you decide whether your observation is physical or chemical change?
A thermometer can help you decide whether your observation is a physical or chemical change by measuring the temperature change. A physical change typically involves a change in state (solid, liquid, gas) without changing the chemical composition, so the temperature may remain constant. In contrast, a chemical change usually involves the breaking and forming of chemical bonds, which can result in a temperature change.
When a candle burns in air which change occurs first-physical or chemical?
chemical change occurs first. because first oxygen help in burning and form carbon-di-oxide which is a chemical change

How can you identify that a change is chemical?
A change is chemical if the substance's chemical composition is altered, resulting in the formation of new substances with different properties. Look for indicators such as color change, gas production, temperature change, or formation of a precipitate to help identify a chemical change.
Is baking a cake a chemical change?
Yes. This is because when the cake is baked, chemicals help it rise, making this a chemical change. Making the icing is a different story. It is a physical change.

Is burning a pen a chemical change?
Yes, burning a pen is a chemical change because it involves a rearrangement of the atoms in the pen due to the combustion process. New substances are formed during the burning, such as ash and smoke, which are different from the original materials in the pen.
