If you take organic chemistry laboratory (chm2211l) you will learn the term reflux. a reaction is considered to be at reflux when it is set at the boiling point of your solvent. a. in order to bring 74.81 ml of chloroform (density = 1.4832 g/cm3 , c = 0.96 j/g*k ) to reflux from room temperature (25 oc) it requires 1.46 kj of energy. what will be the temperature (in of) of the chloroform?

Answer : The temperature of the chloroform will be,

Explanation :

First we have to calculate the mass of chloroform.

conversion used :

Now we have to calculate the temperature of the chloroform.

Formula used :

where,

q = amount of heat or energy = 1.46 kJ = 1460 J   (1 kJ = 1000 J)

= specific heat capacity =

m = mass of substance = 110.958 g

= final temperature = ?

= initial temperature =

Now put all the given values in the above formula, we get:

Now we have to convert the temperature from Kelvin to Fahrenheit.

The conversion used for the temperature from Kelvin to Fahrenheit is:

As we know that, or,

 ...........(1)

Now put the value of temperature of Kelvin in (1), we get:

Therefore, the temperature of the chloroform will be,

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
