First Law Of Thermodynamics MDCAT Quiz: Energy conservation and its application to chemical and physical processes: This law is the basis for understanding energy transfers within a system and how work, heat, and internal energy are interrelated. MDCAT Quiz section often asks questions regarding energy conservation, so one has to understand this law in order to solve the associated problems.
The first law of thermodynamics, otherwise known as the law of conservation of energy, is a principle in physics and chemistry that postulates that no energy can be created or destroyed, only converted or transferred. This principle forms a very essential foundation for the understanding of dynamics of energy in biological and chemical systems for the MDCAT students. Our all-inclusive MDCAT Quiz on the subject ensures you grasp the central themes of the law, be it energy transfer processes or their applications in a thermodynamic system.

The first law of thermodynamics is a statement of the conservation of:
Energy
The change in internal energy of a system is equal to:
Heat added minus work done
The formula for the first law of thermodynamics is:
ΔU = Q - W
In an isothermal process, the first law of thermodynamics implies that:
Q = W
The work done by a system in a thermodynamic process is:
The area under the PV curve
When a gas undergoes an adiabatic process, the first law implies:
Q = 0
The internal energy of an ideal gas depends on:
Temperature only
The first law of thermodynamics can be expressed as:
ΔU = Q - W
In an adiabatic process, no heat is exchanged, so:
Q = 0
The first law of thermodynamics helps in understanding:
Energy conservation in processes
In the first law of thermodynamics, Q represents:
Heat added to the system
The first law of thermodynamics is applicable to:
Both closed and open systems
The work done in a thermodynamic process is negative when:
The system contracts
In the first law of thermodynamics, the change in internal energy (ΔU) is:
The heat added to the system minus work done by the system
In a reversible process, the first law states that:
ΔU = Q - W
During an expansion, if heat is absorbed, the first law tells us that:
Work is done by the system
For an isochoric process, the work done is:
Zero
The first law of thermodynamics applies to:
All thermodynamic processes
The internal energy of an ideal gas is primarily a function of:
Temperature
The heat capacity of a substance is defined as:
The amount of heat required to raise the temperature by one degree
In a cyclic process, the change in internal energy of the system is:
Zero
The first law of thermodynamics applies to:
Any process where energy is exchanged
In a thermodynamic process, if no heat is added or removed, the system is:
Adiabatic
The work done in an isothermal expansion of an ideal gas is equal to:
nRT ln(Vf / Vi)
The formula for calculating the change in internal energy for an ideal gas is:
ΔU = nCvΔT
The first law of thermodynamics is important for understanding:
Energy conversion efficiency
In the first law, the term W represents:
Work done by the system
The change in internal energy for an adiabatic process is equal to:
The work done on or by the system
The first law of thermodynamics does not apply to:
Non-equilibrium systems
In a thermodynamic system, if heat is added to the system, the internal energy:
Increases
