10.2 Thermodynamics
LO 5.12 I can use representations and models to predict the sign and relative magnitude of the entropy change associated with chemical or physical processes.
LO 5.13 I can predict whether or not a physical or chemical process is thermodynamically favored by determination of (either quantitatively or qualitatively) the signs of both H and S, and calculation or estimation of G when needed. LO 5.14 I can determine whether a chemical or physical process is thermodynamically faborable by calculating the change in standard Gibbs free energy.. |

LO 5.7 I can design, and/or interpret the results of an experiment in which calorimetry is used to determine the change in enthalpy of a chemical process (heating/cooling, phase transition, or chemical reaction) at constant pressure..
LO 5.6 I can use calculations or estimations to relate energy changes associated with heating/cooling a substance to the heat capacity, relate energy changes associated with a phase transition to the enthalpy of fusion/vaporization, relate energy changes associated with a chemial reaction to the enthalpy of the reaction, and relate energy changes to PV work.
How do you design an effective, safe, environmentally benign, and inexpensive hand warmer?

How do you design an effective, safe, environmentally benign, and inexpensive hand warmer?
- Determine which substances, in what amounts, to use in order to meet the criteria listed for the ideal hand warmer.
- Can you generate heat to warm your hands up anytime you want to?
- One type of hand warmer contains water and a solid, soluble substance: as the solid dissolves, the packet becomes warm.
