Two students are trying to figure out the Calories per gram of potato chips. They burn part of the potato chip and feel the heat

. They decide to measure this heat by putting a can of water above the burning potato chip so they can measure the heat gained by the water.
1 Calorie is equal to 1,000 calories

4.184 J = 1 cal

Specific heat of water is 4.184 J/g °C

They collect the following data:


mass of potato chip before burning 0.58 g
mass of potato chip after burning 0.40 g
mass of water in can 50.9 g
initial temperature of water 21.7 °C
final temperature of water 23.8 °C

How many Cal were released by potato chip? Round your answer to 2 decimal places

When compounds are formed, will its heat give off?​
mariarad [96]

Answer: It depends on the type of chemical reaction that formed the compound.

Explanation:

Exothermic reactions give off the heat to the reaction environment, so the compound feels hotter.

Endothermic reactions absorb the heat from the reaction environment and the compound feels cooler.
