Explanation Explanation Record the given data: Molar heat of fusion of benzene = 9.92 kJ/mol. Molar heat of vaporization = 30.7 kJ/mol. The given molar heat of fusion and molar heat of vaporization of benzene are recorded as shown above. To calculate the heat required to melt 8.25 g benzene at its normal melting point. Molecular weight of benzene is 78 .11g . = 8 .25 g benzene× 1mol benzene 78 .11 g × 9 .92 kJ 1 mole benzene = 1 .05 kJ The given heat of fusion of benzene and molecular weight of benzene are plugging in the equation to give heat required to melt 8.25 g benzene. The required heat for melt 8.25 g benzene is 1 .05 kJ

Ideal and Real Gases

Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,

Gas Laws

Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries we…

Gaseous State

It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed fo…
