**Physics Question****Topic: Thermodynamics - Isothermal Processes****Question 36:**During an isothermal process, 5.0 J of heat is removed from an ideal gas. What is the change in internal (thermal) energy of the gas?**Options:**A) 5.0 J B) 10 J C) 0 J D) 2.5 J **Explanation:**In an isothermal process, the temperature of the ideal gas remains constant. According to the first law of thermodynamics, the change in internal energy (ΔU) of an ideal gas is directly proportional to the change in temperature. Hence, for an isothermal process (where the temperature does not change), the change in internal energy is zero. Thus, the correct answer is:**C) 0 J**

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.
