Which chemical change causes a cake to rise?

the main ingredient that helps a cake rise is baking powder (sodium bicarbonate); when it interacts with the heat, it creates a chemical reaction that produces carbon dioxide (tiny bubbles) to allow the cake to be light and fluffy.

This is a type of chemical reaction...exothermic (reaction that produces heat) and endothermic (reaction of taking the heat in).  Endothermic chemical reaction that changes the batter from the thick liquid state to a firm, fluffy state.

Explanation:

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
