Heat using First Law of Thermodynamics Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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

Change in Internal Energy: 900 Joule --> 900 Joule No Conversion Required
Work done in Thermodynamic Process: 250 Joule --> 250 Joule No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = ΔU-W --> 900-250

Evaluating ... ...

Q = 650

STEP 3: Convert Result to Output's Unit

650 Joule --> No Conversion Required

FINAL ANSWER

650 Joule <-- Heat Transferred in Thermodynamic Process

(Calculation completed in 00.020 seconds)

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.

How to Calculate Heat using First Law of Thermodynamics?

Heat using First Law of Thermodynamics calculator uses Heat Transferred in Thermodynamic Process = Change in Internal Energy-Work done in Thermodynamic Process to calculate the Heat Transferred in Thermodynamic Process, The Heat using First Law of thermodynamics formula is defined as difference between internal energy and work into system. in thermodynamics, heat is energy in transfer to or from a thermodynamic system, by mechanisms other than thermodynamic work or transfer of matter. Like thermodynamic work, heat transfer is a process involving more than one system, not a property of any one system. Heat Transferred in Thermodynamic Process is denoted by Q symbol.

How to calculate Heat using First Law of Thermodynamics using this online calculator? To use this online calculator for Heat using First Law of Thermodynamics, enter Change in Internal Energy (ΔU) & Work done in Thermodynamic Process (W) and hit the calculate button. Here is how the Heat using First Law of Thermodynamics calculation can be explained with given input values -> 650 = 900-250.
