The amount of heat at constant volume is called as:
Correct answer: A. Internal energy
- A. Internal energy
- B. Enthalpy
- C. Entropy
- D. Temperature
- E. Pressure
Explanation
At constant volume, the heat of the reaction is equal to the change in the internal energy of the system. Meanwhile, the heat of reaction at constant PRESSURE is known as enthalpy

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.

A system absorbs 1000 Joules of heat and delivers 600 Joules of work, while losing 100 Joules of heat by conduction to the atmosphere, the change in the internal energy of the system will be:
The efficiency of the Carnot's Engine working between 150°C and 50°C is:
A gas is enclosed in a container fitted with a piston of cross-sectional area of 0.10 m2. The pressure of the gas is maintained at 8000 N/m2. When heat is slowly transferred, the piston is pushed up through a distance of 4.0 cm. If 42 J heat is transferred to the system during the expansion, what is the change in the internal energy of the system?
A fixed mass of gas in a thermally insulated container is compressed. After compression, the temperature of the gas will have:
