Designing Instant Thermal Cans
Assessment
Self-heating meals are convenient for anyone away from heating sources. They also help nourish and comfort people in disaster relief situations. This assessment tasks students with using chemical process data to make design decisions for an instant thermal can product. Knowledge, Skills, and Abilities (KSAs): 1. Analyze data to identify whether a chemical process absorbs or releases thermal energy. 2. Design an instant thermal can according to given criteria and constraints that uses chemical processes to transfer heat energy.
Self-heating meals are convenient for anyone away from heating sources. They also help nourish and comfort people in disaster relief situations. Self-heating devices use chemical processes to transfer heat to the food or drink.
