Specific Gravity

Can someone explain to me how it came to be that one gram of water consumes one cubic centimeter of space?

    Thanks Theresa,

    So it was the French in the late 1700s and early 1800s.

    That’s the way it’s defined. It’s as simple as that.

    I wondered if it was a dumb question when I posted it.

    Following Theresa’s link I learned the French, as a part of the effort to standardize weights and measures used in commerce, determined the system should be based upon measurements of the earth, from which the concept of the kilometer derived.

    Subsequently someone decided that one gram of water should be defined as composing a cube measuring 100,000th of a kilometer on each side.

    Hello from your Nephew,

    Theoretically speaking, the conditions of water that you are asking about can only occur at 4 degrees celcius when in liquid form. Quantitatively, density=(mass/volume). With mass in grams and volume in centimeters cubed and the density of liquid water at 4 degrees celcius approximately equal to 1 g/cm cubed, simple algebra when using the formula for density will tell you that 1 gram of water has a volume of 1 cm cubed.

    P.S. Hope all is well, I know some things about science and nothing about politics, so thought I’d comment.

    Hey Ian,

    How nice of you to stop by and for providing an explanation.

    Your mother had mentioned that perhaps she would drag you along on a visit to Mexico. I hope she is able to do so.

    Take care and enjoy the holiday season.

    Saludos a todos. Please tell your dad I said hi and that I wish him well.
