Abstract / Description of output

A physically credible relationship based on the unbalanced Young force between the
initial and receding contact angles of an evaporating droplet is proposed and used to
give a complete description of the lifetime of a droplet evaporating in an idealised
stick-slide mode. In particular, it is shown that the dependence of the lifetime on the
initial contact angle is qualitatively different from that when the relationship between
the initial and receding contact angles is not taken into account.
