11. many metals are described as ductile, which means they can be
o mixed with other metals to form alloys
o hammered into a shape
o drawn into a wire
o broken apart with a sharp blow

Option (3)

Explanation:

Ductility of a substance is defined as the property by which a substance can be hammered and change its form into thin, stretched wires. In simple words, the ductile materials can be drawn into thin wires. Some of the examples of ductile substances are gold, copper and silver.

The rocks also have this property which means that they have the capacity to get deformed into enormous strains in the absence of large scale fracturing.

Thus, the correct answer is an option (3).

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
