If ice is present and carburetor heat is applied, how will engine RPM typically change?

Explanation:
Carburetor ice restricts airflow and reduces engine power. When carburetor heat is applied, warm air is drawn into the carburetor, which melts the ice and restores air flow. However, the warm air is less dense, so at first there is less air entering the engine for the same throttle setting, causing the RPM to drop. As the ice continues to melt and the airflow clears, the engine receives the proper air mass again, and RPM gradually climbs back toward normal (often reaching or exceeding the previous RPM).
