Final temperature
In a lab, the goal was to measure the amount of calories (energy) in a potato chip. First, 60 g of water at 25oC was added to the coke can. Then a potato chip was set on fire under the can. After the chip has stopped burning, the mass of the burned remnants was and the temp of the water has risen to 75oC. What is the temperature change of the water?
-75°C
+50°C
+75°C
-50°C
+25°C

After the chip has stopped burning, the mass of the burned remnants was and the temp of the water has risen to 75oC. How much heat was absorbed by the water?
3000 cal or 3 Cal
5000 cal or 5 Cal
1000 cal or 1 Cal
6000 cal or 6 Cal
