Abstract :
Contact angle, ? (theta), is a quantitative measure of wetting of a solid by a liquid. The contact angle is geometrically defined as the angle formed by a liquid at the three-phase boundary where a liquid, gas, and solid intersect [1]. The study of mine was conducted to know that how the contact angle of water changes when a drop of 0.1 ml of a water drop is subjected to an already heated hard-glass beaker tub. I hypothesized that the contact angle of water must decrease subsequently when we subject it to the already heated equipment with time, but to my surprise I noted that the contact angle kept on increasing when the temperature was increased with time. I was carrying out this research for nearly 2 years to collect all the required data and images to come to this conclusion and derive a general equation by modifying the Young’s equation, to know the contact angle of any liquid when it is being subjected to any heated vessel with time. If my experimental strategy were employed at a larger scale, the data generated could help scientists to better understand the factors on which contact angle of a liquid depends [2].
