A water droplet was slid on an inclined plate whose lower surface was kept at a temperature between room temperature and 510 K. The dependence of the dynamic advancing and receding contact angles on the wall temperature and the contact line velocity was measured from the shape of the droplet sliding on the high temperature surface. The experimental results demonstrate that a rise in the wall temperature increases the dynamic contact angles due to evaporation from the meniscus. The dynamic receding contact angles at high temperatures increase with increasing the receding velocity of the contact line. This result is contrary to the well-known fact at room temperature. The velocity dependence of the dynamic advancing contact angle is similar to the well-known dependence at room temperature.
