Question: 1. A wettability test is done for two different solids: Aluminum and PTFE. The surface free energies were calculated as: Between Al-liquid: 70.3 J/m Between
1. A wettability test is done for two different solids: Aluminum and PTFE. The surface free energies were calculated as: - Between Al-liquid: 70.3J/m2 - Between liquid-vapor: XJ/m2 - Between Al-vapor: 30.7J/m2 - Between PTFE-liquid: 50.8J/m2 - Between liquid-vapor: YJ/m2 - Between PTFE-vapor: 22.9J/m2 Assuming the liquid is distilled water, Please calculate the maximum range of X and Y and restrict the range into a reasonable length of 5J/m2
