Units – cubic meter or cubic centimeter Liter = one cubic decimeter Density = mass/unit volume – ratio compares mass to an object’s volume Example – g/cubic centimeter Temperature – measures (approximately) how hot or cold an object is Kelvin – Freezes at 273k. Boils at 373k. + 273 to Celcius = kelvin
