System balances Categorize the following processes as (i) steady or unsteady(ii) continuous, batch or semi batch. Support your choices with appropriate discussion. Where necessary, perform a calculation. (a) You are making a delicious meal in a crock pot. Consider the cooking process in thecrockpot.
(b) You turned on the hot and cold water taps to ow in at a steady rate and ll the bathtub with perfect constant warm water (tub outlet closed).(c) Water is being lled into a 2000 L tank at a rate of 1 kg/s. There are two streams leaving the tank at a rate of 0.3 kg/s each. The tank is initially half full.
(d) Water is being lled into a 2000 L tank at a rate of 1 kg/s. There are two streamsleaving the tank at a rate of 0.5 kg/s each. The tank is initially half full.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
