Which is the best metal to use in an alloy to increase its electrical conductivity? aluminum (al) silver (ag) zinc (zn) antimony (sb)

Among the given option, Silver (Ag) is the best metal to use in an alloy to increase its electrical conductivity.

Explanation:

Aluminium has a very high conductivity for electricity but the metal has very low tensile strength, alloy is made to harden it but that results in decreased conductivity. Silver has very high electrical conductivity.

When it is mixed with copper to form an alloy, becomes a very good conductor and a strong alloy for the electrical goods. Zinc has a very low electrical  conductivity. Antimony is a very strong metal but doesn’t have any electrical conductivity.

4046atm

Explanation:

For this question you can use the ideal gas law,

Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.

Because of the units given, R will equal .08026

Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):

This will give you:
