2. Why does exhaled air make the limewater milky?
Answers
Answer:
Hey mate your answer
Limewater can be used to detect carbon dioxide. If carbon dioxide is bubbled through limewater then it turns from clear to cloudy/milky in colour. ... After a few breaths the limewater in tube B will turn cloudy as the exhaled air contains more carbon dioxide.
Explanation:
hey mate your answer is given in above mentioned 2 images and in text form.
Investigating respiration
Respiration by living organisms can be investigated by carrying out experiments to show the production of carbon dioxide and heat.
Limewater can be used to detect carbon dioxide.
Breathing in through the mouthpiece draws air from the atmosphere in through tube A. Breathing out through the mouthpiece bubbles exhaled air through tube B. After a few breaths the limewater in tube B will turn cloudy as the exhaled air contains more carbon dioxide.

Answer:

our exhaled air is full of carbondioxide so the lime water became milky.
