Assertion A : If dQ and dW represent the heat supplied to the system and the work done on the system respectively. Then according to the first law of thermodynamics dQ=dU−dW.Reason R : First law of thermodynamics is based on law of conservation of energy.In the light of the above statements, choose the correct answer from the option given below :A is correct but R is not correctA is not correct but R is correctBoth A and R are correct and R is the correct explanation of ABoth A and R are correct but R is not the correct explanation of A

Which of the following best describes the first law of thermodynamics?a. energy can be created but not destroyedb. energy cannot be created but can be destroyedc. energy cannot be created or destroyedd. energy can transfer from one form to anothere. both c and d

If the amount of work done (W) is the same as the amount of energy transferred in by heat (Q), the net change ininternal energy is 1

Based on the first law of thermodynamics, which one of the following is correct?(a) For an isothermal irreversible change , q = +w(b) For an isochoric process, ΔU = -q(c) For an adiabatic process, ΔU = -w(d) For isothermal irreversible change , q = -w

Select the statements below that express the first law of thermodynamics. There could be more than one correct answers.Group of answer choicesHeat flows in the direction of decreasing temperatureEnergy can neither be created nor destroyed.The change in the total energy for a closed system during an adiabatic process must be equal to the net work input.Energy is conservedEnergy has quality as well as quantity
