    In this paper, we have investigated the influences of heating surfaces, using copper, brass, stainless steel, nickel-plated, and chromium-plated heating suffaces. We found that, brass surface gave the highest a, while chromium-plated surface the lowest. This can be explained by the fact that the contact angle between liquids and metallic surfaces are different.
