N the calibration step of a thermochemistry experiment, a current of 124\text{ mA}124 mA, from a 24.0\text{ V}24.0 V source was allowed to flow through the electrical heater for 219\text{ s}219 s and was found to result in an increase in the temperature of the calorimeter and its contents of +1.39\text{ K}+1.39 K. Given that the energy supplied by an electrical circuit is the voltage multiplied by the current, multiplied by the time, what is the heat capacity of the calorimeter and its contents?

The law of entropy can also be called the law of increasing disorder, but this law seems to contradict the existence of living organisms that are able to organize chemicals into organic molecules. prepare for a class debate on the validity of the following arguments: a. living things are not subject to the laws of thermodynamics. b. the increase in the universe's entropy due to life processes is greater than the decrease in entropy within a living organism.
