ABSTRACT:

One of the techniques for the determination of the specific heat of liquids use the Newton's law of cooling for the analysis of the experimental data. To accurately determine the specific heat of aniline, taking care in experiment design to eliminate sources of random and systematic error. The cooling method is very much effective to calculate the accurate specific heat of a liquid. For this, the students have to very careful for reading of temperature otherwise the percentage of error will rise.

INTRODUCTION

Pacific heat is the amount of heat needed to raise the temperature of one kilogram of mass by 1 kelvin. Heat capacity is an extensive property of matter, meaning it is proportional to the size of the system.[1]

Basically, in the liquid, the method of transformation is convection. By which method, the heat transferred. From the heater point to cooler point by the molecule of the matter is called convection. [2]

Convention will take place if there exists a temperature gradient in a stationary fluid medium. The experiment was conducted to determine the thermal conductivity of liquid (Aniline).

Basically the experiment has due to know how to find the specific heat of a liquid. We can understand the way of finding the specific heat of a unknown matter following the law of Newton which is known as cooling method.

THEORY

(1) HEAT. When an amount of energy is transferred from one body to another solely as a result of the temperature differences between the bodies, we call that amount of energy "heat." Bodies can transfer energy in this way through three processes: radiation, conduction, or convection. When, due to the heat transfer, the hotter body loses thermal energy and a cooler one gains that same amount of thermal
