A certain sample of gas has a volume of 20.00 dm3 at 0°C and 1.000 atm. A plot of the experimental data of its volume against the Celsius temperature, ?, at constant p, gives a straight line of slope 0.0741 dm3 (°C)?1. From these data alone (without making use of the perfect gas law) determine the absolute zero of temperature in degrees Celsius.
It's not until death that the percentage of carbon-14 will begin to diminish from decay. Because radioactive decay is a first-order process, the integrated rate law for a first-order reaction can be rewritten asfraction remaining
