a physical change is reversible like freezing or melting but a chemical change is irreversible like baking a cake, once it's been cooked, you can't get your cake mix bake
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
Burning, rusting, and production of gas are examples of chemical changes.
Chemical - a physical change can be reversed , e.g Freezing water, melting chocolate. But something like popping corn is ireversible like baking a cake or boiling a egg. Hope this helps.
Baking powder is typically used to make cakes rise. Baking powder is essentially, baking soda with an additional acid. When it reacts, it breaks down into carbon dioxide, water, and salt. The carbon dioxide causes bubbles in the cake mix, allowing the cake to rise.
physical change
Baking is a chemical change.
Grinding coffee beans is a physical change as it does not change the chemical composition of the beans.
Chemical change.
When a cake is baked it changes its physical appearance and is thus said to undergo a physical change.However there are many concurrent chemical changes:sugars caramelizeproteins coagulateleavening agents (baking soda etc.) release carbon dioxidestarches, oils and fats oxidize
It's mostly a chemical change - since I doubt it is reversible.
Baking is a chemical change
It is a physical change as it can be "undone" by evaporating the water. An simple example of a chemical change is baking a cake, you can't un-bake a cake. To work out whether it is a chemical or physical change just think whether it can be undone or not.
Baking a cake is a chemical property because it is going from dough to cake or batter to cake.
Baking is a chemical change because involve chemical reactions.
pretty sure its a chemical change.
Baking a cake is a chemical change because the ingredients undergo a chemical reaction when exposed to heat, resulting in a transformation of their molecular structure to form the cake. This is different from a physical change, which does not alter the composition of the ingredients.
