Formula in Code Format
def calculate_evaporation_rate(volume_ml, alcohol_percentage, room_temperature_C, time_hours):
evaporation_factor = 0.1
temperature_factor = (room_temperature_C - 20) * 0.05
evaporation_rate = volume_ml * (alcohol_percentage / 100) * evaporation_factor * (1 + temperature_factor) * time_hours
