    A physical property of a material that describes its resistance to uniform compression. It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume.

    • The bulk modulus of water is about 2.2 GPa.
    • Engineers use the bulk modulus to predict how a material will behave under high pressure.
    • Diamonds have an exceptionally high bulk modulus, making them very hard to compress.
