    Why are unsaturated fats liquid at room temperature and saturated aren't?
    I know that it has something to do with the unsaturated fats having double bonds which create kinks, But how does this make it liquid at room temperature?

    well erm all I can add is that they're more stable at room temp as they don't combine readily with oxygen and the straight unbranched chains of hydrocarbons is also why they're solid..like you said no kinks....

    C=C bonds create kinking shape and the packing efficiency is lowered, lowering the intermolecular forces.

    hafnium is right- the straight unbranched chains increase van der Waals' forces increasing melting point of the substance and hence causing it to be solid at room temperature as opposed to liquid.

    Hope it helps! This is from a chemistry perspective though
