The downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.
<h3>Can titanium withstand temperatures?</h3>
Titanium alloys have high tensile strength to weight ratio, good toughness and an ability to bear extreme temperatures of more than 600 °Celsius. This shows that if temperature increase from more than 600 °Celsius, the strength of the titanium tends to decrease because it can not withstand to it so the graph comes to downward when the temperature exceeds to 600°C.
So we can conclude that the downward slope represents the relation between durability of titanium and temperature because with increase temperature, strength of titanium decreases.

Answer:
12.8 g of 
must be withdrawn from tank
Explanation:
Let's assume gas inside tank behaves ideally.
According to ideal gas equation- 
where P is pressure of , V is volume of , n is number of moles of , R is gas constant and T is temperature in kelvin scale.
We can also write, 
Here V, T and R are constants.
So, 
ratio will also be constant before and after removal of from tank
Hence, 
Here, 
and 
So, 
So, moles of must be withdrawn = (0.66 - 0.26) mol = 0.40 mol
Molar mass of = 32 g/mol
So, mass of must be withdrawn =
