option (a)
Explanation:
In an isothermal process, the temperature of the gas remains constant.
The internal energy of the gas is the function of change in temperature.
As the temperature is constant, so there is no change in the internal energy of the gas.
So, internal energy change is zero.
Answer:
I would say it is recycling nonrenewable minerals instead of throwing them away.

The orbit of a space shuttle is surprisingly like an apple falling from a tree to earth. The space shuttle is simply moving so fast that the path of its fall is an orbit around our planet. Which of Newton’s laws helps explain the orbit of a space shuttle around earth and the orbit of earth around the sun
