In an isothermal process, 1.59 moles of an ideal gas is compressed to one-fifth of its initial volume at 285 K. What quantity of heat is added to, or removed from, the system during this process

−6063.54 J  of heat is removed from the system during this process.

Explanation:

Given that :

in an isothermal process

number of moles of an ideal gas =  1.59 moles

which is compressed to one- fifth of its initial volume

Let say the initial volume = x

the final volume will be = x/5

Temperature = 285 K

The objective is to determine what quantity of heat is added to, or removed from, the system during this process.

In an isothermal process;

q = w

where ;

w = nRT In (V₂/V₁)

w = 1.59 × 8.314 × 285 × In (x/5 /x)

w = 1.59 × 8.314 × 285 × In (1/5)

w = −6063.54 J

Thus;  −6063.54 J  of heat is removed from the system during this process.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
