Saturated fats are solid at room temperature, while unsaturated fats are liquid at room temperature. This is because saturated and unsaturated fats differ in their chemical structures. Saturated fats have no double bond between molecules, which means there are no gaps and the fat is saturated with hydrogen molecules. On the other hand, unsaturated fats have double bonds, which break up the chain of hydrogen molecules and create gaps, allowing the fats to liquefy at room temperature, according to registered dietitian Anne VanBeber, Ph.D, professor and chair of nutritional sciences at Texas Christian University.

A saturated compound consists of those carbon atoms which are linked together by single bond (i.e. consisting one sigma bond).
An unsaturated compound consists of those carbon atoms which are linked together by double bond (i.e. consisting one sigma bond and one pi bond) or by triple bond (i.e. consisting one sigma bond and two pi bonds).
The saturated compounds are known as alkanes(single bonded), whereas the unsaturated compounds are known as alkenes(double bonded) and alkynes(triple bonded).
Let's take a simple example for better understanding-->
(1). Propane (it is a saturated compound)
Structure---> CH3-CH2-CH3
It can be clearly seen that the carbon atoms in the chain are connected with a single bond, so it is a saturated compound.
(2). Propene (it is an unsaturated compound)
Structure---> CH2=CH-CH3
Now in this structure, the first and second carbon atoms are bonded together by a double bond and the second ans third carbon atoms are bonded together by a single bond, there is a double bond in this compound so we can say this in an unsaturated compound.
(3). Propyne (it is an unsaturated compound)
Structure---> CH3-C≡CH
In this compound the first and second carbon atoms are connected by a single bond but the second and third atoms are connected by a triple bond , and due to thr triple bond present in the compund we can say that it is an unsaturated compound.
