Solution

Shape of an object is changed by applying force. It changes the relative position of particles inside the lattice. Force is given by $F = m a$ where, is mass and a is acceleration .
Force acting per unit area is called as pressure $P = \frac{F}{A}$ where, F is applied force and A is perpendicular area.
