Matter and Temperature Quick Check
1. What is matter?
- Matter refers to anything that has mass and takes up space.
2. What are the three states of matter?
- The three states of matter are solid, liquid, and gas.
3. How does temperature affect matter?
- Temperature affects matter by causing it to change state or expand and contract in volume.
4. What is temperature?
- Temperature refers to the degree of hotness or coldness of an object or substance.
5. What is the SI unit of temperature?
- The SI unit of temperature is Kelvin (K). Other common units include Celsius (°C) and Fahrenheit (°F).
