Final answer:
Water, pizza, and oxygen are types of matter as they have mass and occupy space. Electricity is not matter since it's a form of energy. Coffee, tea, and hydrogen are categorized by chemists as solutions and an element respectively, while an egg is a complex system of multiple substances.
Step-by-step explanation:
When considering food and drink items in relation to matter, it's important to recognize that matter is defined as anything that has mass and takes up space. Among the options provided (water, pizza, oxygen, electricity), water (a), pizza (b), and oxygen (c) are forms of matter, as they all possess mass and occupy space. On the other hand, electricity (d) is a form of energy rather than matter, as it does not have mass and does not take up space in the traditional sense.
From a chemist's perspective, these examples can be categorized further:
- Coffee and tea are examples of homogeneous mixtures known as solutions.
- Hydrogen is an element, specifically a gas at room temperature.
- Finally, an egg is considered a system with multiple components, including water in the form of liquid, proteins, and fats, all of which have clear matter properties.
