Timah Tasoh dam in Perlis has the dimensions of 20-m high and 770-m wide. It is filled with water of density equals to 1000 kg/m² and gravitational force equals to 9.81 m/s?.

(i) Name the property of fluid that allow this situation to happen with its symbol. (ii) The soap bubble flew into the air and makes a diameter of 5 cm. If the surface tension of the soap solution in air at 1 atm and 20°C is 0.025 N/m, calculate the gauge pressure inside it.
