An ideal gas is compressed to half its initial volume by means of several possible processes. which of the following processes results in the most work done on the gas? a. adiabatic b. isobaric c . isothermal d. the work done is independent of the process.

Option a. Adiabatic

Explanation:

Adiabatic system is one in which there is no exchange of mass and heat in between the system and its surrounding and the only transfer is in the form of work done.

In this process the internal energy of the system depends on the temperature and increases with the increase in temperature and as there is no exchange of heat between surrounding and system temperature as well as internal energy of the thermodynamic system increases.

Therefore, the work done not only compresses the gas but it is utilized in raising system's internal energy.

Thus, it is in adiabatic process that results in most work done on the gas.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
