For example, describe a change in mass, volume, state or shape where the original substance has not been chemically changed. Be specific and give details.

Physical Changes in a Holiday Feast

One example of a physical change that can be observed in a holiday feast or over Thanksgiving break is the process of cooking a turkey. When a raw turkey is placed into the oven, it is typically light in color, with a somewhat rubbery texture. However, as it cooks, the turkey undergoes several physical changes.

Cooking a Turkey

As the turkey cooks, its mass decreases due to the evaporation of water content within the turkey. This loss of moisture results in the turkey becoming smaller in size and lighter in weight. Additionally, the volume of the turkey decreases as it loses water and shrinks during the cooking process. The state of the turkey changes from raw to cooked, with the texture transforming from soft and rubbery to firm and juicy.

The shape of the turkey also undergoes a transformation during cooking. The turkey initially has a pale appearance, but as it cooks, the skin turns golden brown and becomes crispy. This change in color and texture is a clear indication of the physical changes that occur when cooking a turkey.
