Answer:
Explanation:
When air is first incorporated with a cake mix, its mass has increased from the mass of the ingredients used - air's mass is also added to the mixture (this helps it rise). Now, if air escapes from the cake as it rises (due to the kinetic energy of the gas particles increasing via convection current), the mass of the cake will decreases as more gas particles have the energy to escape the cake batter as the time to bake the cake increases more will try to escape
