Heat using First Law of Thermodynamics Solution

Follow our step by step solution on how to calculate Heat using First Law of Thermodynamics?

FIRST Step Consider the formula

Q = ΔU - W

Next Step Substitute values of Variables

∴

Q = 900J - 250J

Next Step Prepare to Evaluate

∴

Q = 900 - 250

LAST Step Evaluate

∴

Q = 650J

How to Evaluate Heat using First Law of Thermodynamics?

Heat using First Law of Thermodynamics evaluator uses Heat Transferred in Thermodynamic Process = Change in Internal Energy-Work done in Thermodynamic Process to evaluate 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 evaluate Heat using First Law of Thermodynamics using this online evaluator? To use this online evaluator for Heat using First Law of Thermodynamics, enter Change in Internal Energy (ΔU) & Work done in Thermodynamic Process (W) and hit the calculate button.
