I thusly taper the beaker onto the burner stand. I took the temperature of the urine supply ahead hot pantsing it up. I low gear started with the marshmallow. I put the mar shmallow onto the fork and noted its weight. Then I lit the marshmallow on brush off and place it under the beaker. after the set fire to was extinguished I measure the temperature of the piss and recorded it. I thus place the remains of the marshmallow and fork onto the scale and recorded my findings.

By hands on burning or the food and taking the date that we find and putting it into equations to find what is needed. Procedure After organizing all the equipment necessary to perform the lab correctly and safety, I placed the empty beaker on to the scale and recorded the weight.Then I filled the beaker with 50 ml of water and measured it and recorded my results. I then place the beaker onto the burner stand. I took the temperature of the water before heating it up. I first started with the marshmallow. I put the marshmallow onto the fork and measured its weight. Then I lit the marshmallow on fire and place it under the beaker. After the flame was extinguished I measure the temperature of the water and recorded it. I then place the remains of the marshmallow and fork onto the scale and recorded my findings. I proceeded to do the same thing with a walnut and then with a potato trip and recording the results of each.Observations and Results Data Table 1 Food Item Observations Food Item Description Marshmallow Walnut Potato Chip Mass of food & holder initial 40. 4g 18. 3 g 16g Mass of food & holder final 38. 8g 16. 3g 13. 5g Mass of food burnt 1. 6g 2g 2. 5g Mass of beaker 66. 5g 66. 4g 66. 5g Mass of beaker & water 107. 2g 108. 2g 108. 2g Mass of water 40. 7g 41. 8g 41. 7g Water temp. initial 23 degrees C 22 degrees C 22 degrees C Water temp. final 31 degrees C 72 degrees C 32 degrees C Delta T (oC change) 8 degrees C 50 degrees C 10 degrees CConclusions From the hands on experience of doing this experiment, I have been able to better understand the formula to find the energy release per gram and to properly put the information into the equation.
