3.9 x 10³g
Explanation:
Given parameters;
concentration = 48g/m³
Room dimension = 12 x 12.5 x 18.5ft
unknown:
Mass of carbon dioxide in the room = ?
Solution:
We know that in a room the concentration of carbon monoxide is 48g/m³
To find the mass of the carbon monoxide in a given room, we simply multiply the given concentration level with the volume of the room.
Mass of carbon monoxide = concentration x volume of room
To find the volume of room;
Dimension = 12 x 12.5 x 18.5 in ft to m;
1ft = 0.31m
12ft to meter is 0.31 x 12 = 3.72m
12.5ft to meter is 0.31 x 12.5 = 3.88m
18.5ft to meter is 0.31 x 18.5 = 5.74m
Volume of the room = 3.72 x 3.88 x 5.74 = 82.8m³
Mass of carbon monoxide = concentration x volume of room
Mass of carbon monoxide = 48 x 82.8 = 3.9 x 10³g

Answer : The current will flow more easily and quickly through the copper wire, on application of voltage because copper is a metal which is good conductor of heat and electricity.
In case of germanium it is a semi-conductor means it will behave as a conductor under certain circumstances.
So if we take same length and same thickness of both the wires, current is more likely to flow through the copper wire than the germanium wire.
