An experimental study is presented to determine the
influence of liquid pool temperature on splashing
behavior. Water droplets with initial diameter of 3.1 mm
+ 0.1 mm impacted a water pool 40 mm in depth. The
impaction process was recorded using a high-speed
digital camera at 1000 frames per second. The impinging
droplet was fixed at room temperature and the liquid
surface was heated using a hotplate. To determine the
critical We number for splashing, the impact velocity
was varied. The critical impact Weber number for
splashing was found to be dependent on liquid pool
temperature, decreasing with an increase in surface
