A cooking appliance includes a controller for establishing a plurality of operating modes for heating an oven cavity. Specifically, the controller establishes one of a pre-heat mode, a ready mode, a first low power mode and a second low power mode for controlling a temperature of the oven cavity.

A new adiabatic scanning calorimeter allows the thermal mass of a high-pressure reaction vessel to be dynamically compensated during a test. This allows the effective Φ factor for the experiment to be reduced to 1.0 without the use of complex pressure balancing equipment.
