- A wet towel exists
- A towel is a kind of object
- So, a wet towel is a kind of wet object

- A wet towel is a kind of wet object
- A wet object contains water
- Therefore, a wet towel contains water

- The wet towel is in the sun
- If an object is in the sunlight then that object will absorb solar energy
- A wet towel is a kind of object
- So, the wet towel will absorb solar energy

- The wet towel will absorb solar energy
- Absorbing sunlight causes objects to heat
- A wet towel is a kind of object
- So, the wet towel will heat

- A wet towel contains water
- The wet towel will heat
- Heating the wet towel will also heat the things it contains
- Therefore, the water will heat

- The water will heat
- Heating means increasing heat energy
- So, the water will increase heat energy

- The water will increase heat energy
- Water is a kind of liquid
- Evaporation means a substance changes from a liquid into a gas by increasing heat energy
- Therefore, the water will evaporate

- Evaporation causes amount of liquid to decrease
- Drying means the amount of liquid decreases
- Hence, evaporation causes liquids to dry

- A wet towel contains water
- The water will evaporate
- Evaporation causes liquids to dry
- Therefore, the wet towel will dry because the water in the towel evaporates

Therefore, the wet towel will dry because the water in the towel evaporates
Question
