Giant Molecular Clouds (GMCs) are sites of the majority of star formation in a galaxy. Observations of GMCs have shown they have a wide range in properties such as mass, radius and star formation efficiency (SFE). The origins of this diversity in SFE is not yet understood. I will show, using high resolution hydro+N-body simulations of an isolated Milky Way-like galaxy, that the observed scatter in SFEs of GMCs can be reproduced using a simple Schmidt star formation law. Further more I will explore:
How stellar feedback can affect the properties of GMCs.
How GMCs evolve over through time, linking the evolution to the measured GMC SFE.
