Question

Which statement best describes the isothermal process? A. the temperature remains constant B. the temperature increases at a constant rate C. heat flows at a constant rate into the system D. heat flows at a constant rate out of the system E. heat flows into or out of the system

Answer 1

Answer: Option (A) is the correct answer.

Explanation:

An isothermal process is defined as the process in which temperature of a system remains constant. In an isthermal process, $\Delta T$ = 0.

When an outside thermal reservoir is in contact with a system then very slow change in the system will occur in order to allow the system to continue adjusting to the reservoir's temperature through exchange of heat.

Hence, we can conclude that the temperature remains constant, best describes the isothermal process.

Answer 2

Answer:

The answer would be A. - the temperature remains constant

Explanation:

An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0
