Polymers are used to make fabrics. Table 1 shows some properties of two polymers.
Polymer fabrics are used to make firefighter uniforms.
Complete Table 2 by deciding for each property whether polymer J or polymer K is best for firefighter uniforms. Use Table 1.
Density has been completed for you. Select the best option for the other three properties.

To determine the best polymer for a firefighter uniform, we need to consider the demands of the job: - **Density:** Lower density (Polymer J) is better as it makes the uniform lighter and less tiring to wear. (This was already completed in the question). - **Melting point:** A high melting point is essential to protect the firefighter from heat. Polymer K has a much higher melting point (260 °C vs 165 °C), so it is better. - **Flame resistance:** The uniform must not catch fire easily. Polymer K has 'Good' flame resistance, while Polymer J is 'Poor'. Polymer K is the clear choice. - **Water absorption:** A uniform that absorbs a lot of water becomes very heavy and cold. Low water absorption is better. Polymer J has 'Low' water absorption, making it the better choice for this property.
