A cake rises as it bakes due to the production of carbon dioxide gas, which is a result of the chemical reaction between baking powder (or baking soda) and acidic ingredients in the batter. When exposed to heat, these leavening agents release gas bubbles that become trapped in the batter, causing it to expand and rise. This process also contributes to the cake's light and fluffy texture.

When a new substance is produced is it a chemical or physical change?
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.

Is it a physical or chemical change. Acids produced by bacteria in plaque cause teeth to decay?
This is a chemical change because the acids produced by bacteria in plaque are reacting with the minerals in the teeth, breaking them down and causing decay.
Is a bomb exploding a physical change?
An atomic bomb uses fission-- the splitting of atoms. It is purely a physical change, at first. Any gases produced in the air surrounding the explosion (which occurs before it touches the ground), along with the intense heat produced, causes chemical changes in the air.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Is heat produced when two liquids are mixed a physical change?
No and yes. If the two liquids do not react chemically then its a physical change, called the enthalpy of mixing, heat of mixing, which can be exothermic or endothermic. If the two liquids react then the heat produced would be chemical.
What are properties of chemical change?
The properties of a Chemical change are these : A) Something new is produced- Preciptiate, Smoke, Colour. B) Light or heat is given off. [ Example- Crumbling of a brownie is a physical change, because nothing new is produced. but when you are baking the brownie, it is a Chemical change, because heat is given off.
Is grilling of milkfish a chemical or physical change?
Grilling milkfish is a chemical change because the heat causes the proteins in the fish to denature and undergo chemical reactions that change its composition and flavor.
A glowing splint placed in a test tube causes a loud pop Is this chemical or physical change?
The loud pop indicates a chemical change. The glowing splint caused a reaction that produced a gas (likely oxygen or hydrogen) leading to the noise. This transformation is a result of a chemical reaction and not just a physical change.
Does chemical change occur when a new substance is produced?
Chemical Change.
Is toasting bread a chemical change or a physical change?
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
