If we want to raise the temperature of one mole of an ideal gas by one kelvin we have to provide how much amount of energy?
Correct answer: D. 0.0821 dm³-atm
- A. 0.0821 joules
- B. 8.314 dm3-atm
- C. 0.0821 KJ
- D. 0.0821 dm³-atm
Explanation
One mole of an ideal gas at 273.16 K and one atmospheric pressure and its temperature is increased by 1K, then it will absorb 0.0821 dm³-atm of energy, dm³-atm is the unit of energy in this situation.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
