Abstract Thermal analysis of a solid-liquid phase using cooling curves at various compositions is a method used to obtain the eutectic composition and temperature of naphthalene-biphenyl. The XE was 0.45 and the TE was 310.3K these are slightly different from the theoretical values which are 0.44 and 312K respectively. Results The cooling curves obtained from both groups Group A Group B The table with the mole fraction and the actual masses added. RUN | Group A | Group B | | Naphthalene

divided into a series of sub-processes called phases. The different phases of the compiler are as follows: Phase 1: Lexical Analyzer or Scanner The first phase of the compiler‚ called Lexical Analyzer or Scanner reads the source program one character at a time‚ carving the source program into a sequence of atomic units called tokens. The usual tokens are identifiers‚ keywords‚ constants‚ operators and punctuation symbols such as comma and parenthesis. Each token is a sub-string of the source program
