Your friend wants to know if the self heating could be refined so that the reaction releases more energy. Which of the following modifications would test this? (a) adding more of the chemicals in the reaction to the device and seeing if the food stays hot longer (b) changing the material of the can and seeing if the temperature of the food is lower (c) adding an extra layer to the can and seeing if the chemicals still need to mix with the water (d) Removing the compartment that separates the chemicals and the water and seeing how much gas is produced.
