Triglycerides are formed when three fatty acids are condensed with glycerol with elimination of three moles of water.

Depending upon the chemical composition of fatty acids the triglyceride may exist either in semi solid / solid form or in liquid form.

Fats (semi solid / solid form):

If all the three fatty acids forming triglyceride are saturated then the triglyceride will be in solid state. This is because the long chains of fatty acids are closely packed and increases the intermolecular interactions.

Oils (liquid form):

If one or more of the fatty acid is unsaturated having cis configuration the triglyceride will exist in a liquid state. This happens because the long chains of fatty acid get kinked, resulting in decreasing the interactions between molecules hence exist as a liquid at room temperature.
