False. Thermoplastic polymers can be melted and reshaped multiple times by heating and cooling. They are not permanently fixed in shape like thermoset polymers.

The obese person may find it difficult to lose weight due to multiple factors. Among these factors, genetic and hormonal reasons that affect metabolism and fat storage in the body can be mentioned.

ترجم حلول Ai The smaller the object, the smaller the surface area will be. This statement is generally true. In most cases, as an object decreases in size, its surface area will also decrease. This is because surface area is directly related to the physical dimensions of an object. For example, imagine a cube that is 1cm in size. The surface area of this cube would be 6 square centimeters. If the cube were to be reduced in size to 0.5cm, its surface area would decrease to 1.5 square centimeters. However, it is important to note that this relationship may not hold true in all cases, as the shape and structure of an object can also affect its surface area. Additionally, certain properties of objects, such as fractals, can lead to more complex relationships between size and surface area.
