Let's evaluate each statement regarding density and convection:
1. **Warm liquid sinks and cool liquid rises**: This statement is **not accurate**. In convection, warm liquids (or gases) tend to rise because they are less dense than cooler liquids, which sink.
2. **Heat moves through solid, liquid and gases through convection currents**: This statement is **partially accurate**. Convection currents specifically refer to the movement of heat through liquids and gases, not solids. In solids, heat transfer occurs mainly through conduction.
3. **Substances with a greater density than water will sink, while substances with less density will float**: This statement is **accurate**. Objects or substances that are denser than water will sink, while those that are less dense will float.
4. **Density is how tightly packed particles are in a substance**: This statement is **accurate**. Density is defined as mass per unit volume and describes how closely packed the particles in a substance are.
In summary, the accurate statements are:
- Substances with a greater density than water will sink, while substances with less density will float.
- Density is how tightly packed particles are in a substance.
