Spacesuits don't need to insulate astronauts from extreme temperature changes in space. Question 4 options: True or False

False

Explanation:

The spacesuit protects the astronauts from various range of temperatures from -156°C to 121°C. Spacesuits have insulation as well as heaters. Spacesuits are equipped with thermal control systems to keep the temperature warm for the astronauts. The heaters in the spacesuit increases the temperature during extreme cold. When the astronaut's body temperature rises, the material absorbs the heat. When it drops, the material gives off the heat, providing warmth. Insulators uses micro-encapsulated phase-change materials.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
