For a skillet, used for cooking, do you want a high or low specific heat
High, so that it will need more energy to heat up
Low, so that it will change temperature quickly
The specific heat of water is 4.18 J/g°C.

In the lab, your goal was to measure the amount of Calories per gram in a potato chip. First, 60 g of water at 25oC was added to the coke can. Then a 1.9g potato chip was set on fire under the can. After the chip has stopped burning, the mass of the burned remnants was 1.5g and the temp of the water has risen to 85oC. How many Cal/g are in the chip?
6 Cal/ga
9 Cal/g
11 Cal/g
7 Cal/g
