Explanation:
At room temperature, resistivity of tungsten is 
and the resistivity of aluminium is 
.
Temperature coefficient of aluminium (
) = 
and, 
= 
T = 
= 
So, at aluminium has resistivity which is three times the resistivity of tungsten at room temperature.
The link between the same atom is always non-polar Covalent.Is Covalent because there is no possibility of an atom donating electrons to the other, since they are equal and need the same number of electrons, and is why the formal charge non-polar (electronegativity) of two atoms is equal. When there is no difference of formal charges (dipole moment) between the atoms, the connection is always apolar.
hope this helps!
The pressure of the gas is 246 kPa.
<em>p</em> = 2.43 atm × (101.325 kPa/1 atm) = 246 kPa

See explanation
Explanation:
Chlorine is a member of the halogen family known as a toxic yellowish green gas. Inhalation of chlorine for a prolonged period of time leads to pulmonary edema. If a person comes in contact with compressed liquid chlorine the person may experience frostbite of the skin and eyes.
However chlorine is very useful in water disinfection and is preferred in water treatment because it provides residual disinfection of the treated water.
Chlorine gas may be dissolved in NaOH to form oxochlorate I which is used as a bleach in cleaning.
Answer: Cornea
Explanation: The cornea is the only part of a human body that has no blood supply as it gets oxygen directly through the air.
