Internal Energy using First Law of Thermodynamics Solution

STEP 0: Pre-Calculation Summary

Formula Used

Change in Internal Energy = Heat Transferred in Thermodynamic Process+Work done in Thermodynamic Process
ΔU = Q+W
This formula uses 3 Variables

Variables Used

Change in Internal Energy - (Measured in Joule) - The Change in Internal Energy of a thermodynamic system is the energy contained within it. It is the energy necessary to create or prepare the system in any given internal state.
Heat Transferred in Thermodynamic Process - (Measured in Joule) - Heat Transferred in Thermodynamic Process is the form of energy that is transferred from the high-temperature system to the low-temperature system.
Work done in Thermodynamic Process - (Measured in Joule) - Work done in Thermodynamic Process is done when a force that is applied to an object moves that object.

STEP 1: Convert Input(s) to Base Unit

Heat Transferred in Thermodynamic Process: 600 Joule --> 600 Joule No Conversion Required
Work done in Thermodynamic Process: 250 Joule --> 250 Joule No Conversion Required

Internal Energy using First Law of Thermodynamics Formula

Change in Internal Energy = Heat Transferred in Thermodynamic Process+Work done in Thermodynamic Process
ΔU = Q+W

What is the Sign Convention for Heat and Work?

Heat Q and work W always refer to the system, and the choice of sign for numerical values of these quantities depends on which direction of energy transfer with respect to the system is regarded as positive. We adopt the convention that makes the numerical values of both quantities positive for transfer into the system from the surroundings.

What is First Law of Thermodynamics?

In a closed system undergoing a thermodynamic cycle, cyclic integral of heat and cyclic integral of work are proportional to each other when expressed in their own units and are equal to each other when expressed in the consistent (same) units.
