The drift speed is defined as `v_(d)=(Delta l//Delta t)`where `(Delta l)is the distance drifted in a long time `(Delta t).`Why don't we define the drift speed as the limit of `(Delta l//Delta t)`as (Delta t (rarr)0)?

Derive the equation, DeltaG = DeltaH - T DeltaS .

The expression [ Delta E//Delta T]_(V) represent

What is significance of T DeltaS in DeltaG = DeltaH - T DeltaS ?

Comment on the spontaneity of a process when DeltaH lt 0, T Delta S gt 0

Comment on the spontaneity of a process when DeltaH gt 0, T Delta Sgt 0 and T DeltaS lt DeltaH

Comment on the spontaneity of a process when Delta H gt 0, T Delta S lt 0

The entropy change at a given temperature is expressed as: q = T DeltaS DeltaS = q//DeltaT DeltaS = q - T S = q//T

How does T DeltaS determine the spontaneity of process?

For which of the following cases, DeltaS = (DeltaH)/(T) ?

A quantity X is given by epsilon_(p) L(delta V)/(delta t) , where epsilon_(p) is the permitivity of free space ,L is a length , delta V is a potential difference and deltat is a time interval . The dimensional formula for X is the same as that of
