Gasoline evaporates before water at the same temperature. This is because

• Gasoline has more Kinetic Energy

• Gasoline has weaker molecular attraction

• Water has more Kinetic Energy

• Water has weaker molecular attraction

Water undergoes Condensation before Gasoline at the same temperature. This is because

• Gasoline has more Kinetic Energy

• Gasoline has stronger molecular attraction

• Water has more Kinetic Energy

• Water has stronger molecular attraction

Water freezes before Gasoline at the same temperature. This is because

• More KE has to be removed from Gasoline

• Gasoline has stronger molecular attraction

• More KE has to be removed from Water

• Water has weaker molecular attraction

Candle wax melts before a Water Ice Cube at the same temperature. This is because

• More KE has to be added to Candle wax

• Candle wax has stronger molecular attraction

• Less KE has to be added to Water

• Water has stronger molecular attraction
