1. Real World Examples of Osmosis

2. Example 1 Sore throat? Gargle salt water. Why? swelling throat tissues, contain H 2 O salt water has lower concentration than throat tissue so by osmosis, water moves from throat tissues out to the salt water loss of H 2 O decreases the swelling and relieves some pain

3. Example 2 Sticky wooden door? Sticky dresser drawer? when it rains: wood absorbs H 2 O from air due to osmosis (hypotonic) when it is dry: H 2 O is lost from wood, returns to normal condition (hypertonic)

4. Example 3 Why does salt kill slugs? liquids inside slug sent to dilute the salt and maintain mucus layer salt will dehydrate slug’s body cause the slug to die because all the liquids would leave its body (hypertonic)
