To demonstrate transient heat transfer, a turkey, which is modeled by a sphere, is cooked in a standard oven. Use sliders to set the mass of the turkey, the oven temperature, and the cooking time. The temperature of the turkey versus the distance from its center is plotted in black. The green dashed line represents the minimum safe temperature for the center of the turkey and the red dashed line represents the maximum acceptable temperature of the outer surface of the turkey. The black curve, representing the temperature profile, should be between these lines. Once the temperature at the center of the turkey is above the green line, the pop-up timer (green and white) goes off. If the center temperature goes above the red line, the turkey catches fire and dinner is ruined. Use the button to change the units from

°C

and kg to

°F

and lbs. If the turkey is stuffed, the cooking parameters have to be modified.
