The change of volume is defined as the difference of two values of volume at different points in time

delta V

Definition: delta V = V(t2) – V(t1)

t1: earlier moment, t2: later moment

delta_V: change of volume (from t1 to t2). If the rate of change is constant, the change is calculated simply by

     delta_V = dV/dt*delta_t ,     delta_t = t2 – t1

In general, the change of volume is determined as the integral of the rate of change of volume over time from t1 to t2.

[delta V] = m^3

rate of change of volume, volume,

If the volume is increasing with time, its change is given a positive value.
