Consider the following statements regarding lapse rate:
1. An unsaturated air mass cools at dry adiabatic lapse rate when it rise in the atmosphere
2. The dry adiabatic lapse rate amounts to `1^(@)C` per 100 meters
3. The wet adiabatic lapse rate may vary between `0.4^(@)C and 0.9^(@)C` per 100 meters
4. Dry adiabatic lapse rate is higher because of the release of latent heat of condensation
