(II) Estimate the Calorie content of 65 $\mathrm{g}$ of candy from thefollowing measurements. $\mathrm{A} 15$ -g sample of the candy is placed ina small aluminum container of mass 0.325 $\mathrm{kg}$ filled with oxygen.This container is placed in 2.00 $\mathrm{kg}$ of water in an aluminumcalorimeter cup of mass 0.624 $\mathrm{kg}$ at an initial temperature of$15.0^{\circ} \mathrm{C}$ . The oxygen-candy mixture in the small container isignited, and the final temperature of the whole system is $53.5^{\circ} \mathrm{C}$

In physics, mechanical energy is the sum of the kinetic and potential energies of a system.

03:47

In physics, the kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest. The kinetic energy of a rotating object is the sum of the kinetic energies of the object's parts.

so in our problem, the 15 grand candy is born and it increased the temperature off. Who? Kilograms of water. A 01375 kilograms off aluminum container. Ondas thereupon 6 to 4 kilograms aluminum calorie meter. These were initially at 15 degrees since years and at the end they are at 53 fined, five decrease. And she is We want to measure the amount of energy contained in a 65 grand candy. So before that, let's find out how much energy is contained within this 15 grand candy. So the amount of heat released by this 15 gram candy it's simply m c Tell Daddy as usual, but in this case we have multiple components. So we have m wants even deal Daddy, Let's aim to see to tell Daddy we can take the bill dirty common because it's the same now for the water masses. Two kilograms. We know that the specific heat of water is one kilo calorie. We're kilogram degrees Celsius. Let's ride on kilogram Here. Bless. We have Placido, which is aluminium. So the mass is there a 0.375 plus 0.624 times. See the specific heat off aluminum. Is there a point to kilocalories for kg degree Celsius? Are you Multiply this whole thing with Jill Dougherty, which is 53.5 minus 15 degrees since years. By flooding this into a calculator, we can see that this is 85.4 Kilocalories notice that there is a decrease and she isn't here. This decree, Celcius and the Kilogram cancel the units. No, because this is the amount of energy and 15 grams off candy. We want to find out how much energy is in 65 grams of candy. We multiplied by 65 by 15 times it's 5.4 which turns out to be 369 kilo calories. But because we have only two significant digits in some places were right, he says. 3 70 kilo calories. This is the amount of energy in the 65 grand candy
