Answer:
(a) 4 %; (b) 5 %
Explanation:
We need a Cu-Ag phase diagram to answer these questions (see diagram). Yours may differ slightly from the one I used.
(a) Cu in Ag
The horizontal red line at 700 °C cuts the right-hand solvus at about 4 % Ag-96 % Cu.
At this point, copper is in equilibrium with the eutectic.
At 700 °C, the maximum solubility of Cu is about 4 % by mass.
(b) Ag in Cu
The horizontal red line at 700 °C cuts the left-hand solvus at about 5 % Cu-95 % Ag.
At this point, silver is in equilibrium with the eutectic.
At 700 °C, the maximum solubility of Ag is about 5 % by mass.
<u>Answer:</u> The thickness of metal sheet is 1.93 mm
<u>Explanation:</u>
The metals sheet is in the form of cuboid.
To calculate the width of the metal sheet for the given volume, we use the equation to calculate the volume of cuboid, which is:
where,
V = volume of metal sheet =
l = length of metal sheet = 15.9 cm
b = width of metal sheet = 14.8 cm
h = height of metal sheet = ? cm
Putting values in above equation, we get:
Converting this thickness into millimeters, we use the conversion factor:
1 cm = 10 mm
So,
Hence, the thickness of metal sheet is 1.93 mm
