A scientist prepared a closed container for a chemical reaction. She poured two liquids into the bottle and quickly closed the bottle with a balloon stopper. The mixture bubbled and the balloon began to inflate. Why did the balloon inflate?

• New substances formed particles that are bigger than the ones before

• The scientist did not seal the system fast enough and more air got in.

• A new gas was created and the gas took up more space.

• The liquids reacted together and created more matter.
