Q. The first law of thermodynamics is

ऊष्मागतिकी का प्रथम नियम है

A
ΔQ = ΔU + W
B
W = ΔQ + ΔU
डब्ल्यू = ΔQ + ΔU
C
ΔU = W – Q
ΔU = डब्ल्यू - क्यू
D
Q = mL
क्यू = एमएल

Explanation

The first law of thermodynamics relates heat, internal energy, and work:

ΔQ=ΔU+W\Delta Q = \Delta U + W

Where:

  • ΔQ\Delta Q = heat added to the system

  • ΔU\Delta U = change in internal energy

  • WW = work done by the system
