Change in entropy of the process is
Explanation:
The entropy of a system is a measure of the degree of disorderliness of the system.
The entropy of a system moving from process 1 to 2 is given as
recall from first law,
hence we have,
since the process is isothermal,
this gives us
integrating within the limits of 1 and 2, will give us
also from ideal gas laws,
hence we have
This makes the correct option B

Answer:
4kg
Explanation:
Given parameters:
Kinetic energy = 1.6J
Velocity = 0.2m/s
Unknown:
Mass of the body = ?
Solution:
The kinetic energy of a body is the energy due to the motion of the body.
It is mathematically expressed as;
Kinetic energy = m v²
m is the mass
v is the velocity
1.6 = x 0.2 x v²
1.6 = 0.1v²
v² = 16
v = 4kg
