Why is butter solid at room temperature?
September 15, 2011 8:21PM
Butter is solid at room temperature because it has a large amount of saturated fatty acids.
Butter is made up of about 51% saturated fatty acids. Saturated fatty acids are molecules that can stretch out straight and stick to other fatty acids around it. As these fatty acids stick to each other, they form a crystalline solid, and room temperature isn't warm enough to melt it.
