Heterogenous mixtures can be separated into their respective constituents by simple physical methods. Identify such methods from the following.
Handpicking
Filtration
Sieving
A heterogenous mixture is one which is made of different substances that remain physically separate. So, the mixture can be separated by physical methods.
Sieving is typically used for separating particles by size through a mesh as we notice near construction sites. Other methods are handpicking and filtration. Distillation is a process used to separate components of a homogenous mixture. It involves heat and a sophisticated apparatus and does not come under 'simple physical methods.'
