## Main Question or Discussion Point

What is Quasistatic process?

the first law of thermodynamics for a quasitatic process:

if it is quasi static

so how come the equation "A" holds true for a quasi static process.

the first law of thermodynamics for a quasitatic process:

dH = δQ + Vdp ------> AdH = δQ + Vdp ------> A

if it is quasi static

**dp**should be very small which can be ignored and hence dH = δQso how come the equation "A" holds true for a quasi static process.
