Yes, lemon water is matter.
What is Matter?
Matter is anything that has mass and takes up space (volume). It's composed of particles, whether they are atoms, molecules, or ions. A chair, air, almonds, and lemon water all fit this definition. Lemon water, being a mixture of water and lemon juice, contains molecules of water (H₂O) and various compounds from the lemon, all of which possess mass and occupy space.
Several sources confirm this:
- Reference 1 & 2: Explicitly state that lemon water is matter because it possesses mass and occupies space and is made up of particles.
Is the Temperature of the Lemon Water Relevant?
The temperature of the lemon water (hot or cold) does not change the fundamental fact that it is matter. Whether it's heated or cooled, the molecules comprising the lemon water still possess mass and volume. References discussing the temperature of lemon water focus on its effects on health or taste, not its classification as matter. These references are irrelevant to answering the core question.
- Reference 3, 5, 6, 7, 8, 9, 10: Discuss various aspects of lemon water consumption, but none contradict its classification as matter.
The Acidity of Lemon Water
The acidity of lemon water (its pH level) is a chemical property, separate from its classification as matter. While lemon juice is significantly more acidic than water, this doesn't negate its status as matter. The reference discussing pH focuses on the acidic nature of lemon juice, not whether it's matter.
- Reference 4: Highlights the acidic nature of lemon juice, but this doesn't change the fact that it's matter.
In conclusion, despite discussions surrounding its acidity and temperature, lemon water unequivocally fits the definition of matter.
