Aresearcher studying the nutritional value of a new candy places a 5.00-gram sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. the observed temperature increase is 2.77 °c. if the heat capacity of the calorimeter is 47.10 kj·k–1, how many nutritional calories are there per gram of the candy?

6236.48 cal/gram

Explanation:

Q= heat released

c = heat capacity of substance      

(1Joule=0.00024kCal)   (1kcal=1000cal)

=Change in temperature= 2.77C= 2.77K

Now heat released per gram of the candy=

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
