Which of the following metals is used in Space Crafts to withstand high temperatures ? A. Fe B. Ti C. Ni D. Pb

The correct answer is titanium (Ti). Titanium is a strong, lightweight metal that is resistant to corrosion and high temperatures. It is often used in space crafts and other applications where high performance is required.

Iron (Fe) is a common

metal that is used in a variety of applications, but it is not as strong as titanium and is not as resistant to high temperatures. Nickel (Ni) is a strong, corrosion-resistant metal that is often used in coins and other applications where durability is important. However, it is not as resistant to high temperatures as titanium. Lead (Pb) is a soft, heavy metal that is not as strong as titanium and is not as resistant to high temperatures. It is often used in batteries and other applications where its low density is important.

In conclusion, titanium is the best metal to use in space crafts because it is strong, lightweight, and resistant to high temperatures.
