Digby wants to determine how many calories are in his bag of chips. Which calorimeter should he use? coffee cup calorimeter bomb calorimeter He could use both types of calorimeters. He cannot use either.

B. bomb calorimeter

Explanation:

The bomb calorimeter is an insulated device that is designed to measure the amount of heat that goes off or is absorbed in a reaction. The device is made in such a way that its internal temperature remains constant. A water bath is placed in the device and heat change in the water bath, the stainless steel and thermometer inside the bomb calorimeter, as well as the actual heat change that occur as a result of the reaction, are all measured to determine the true calorie content of the substance being measured.

A calorie is the amount of energy that is needed to increase the temperature of 1 gram of water by 1 degree celsius. The bomb calorimeter is used to measure the number of calories contained in packaged foods. So Digby can use this device to determine how many calories are in his bag of chips.  

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
