- When the temperature of a solid metal increases,
A.
Strength of the metal decreases but ductility increases |
B.
Both strength and ductility of the metal decreases |
C.
Both strength and ductility of the metal increases |
D.
Strength of the metal increases but ductility decreases |
Answer : Option A
Explanation :
When the temperature of a solid metal increases, its intramolecular bonds are brake and strength of solid metal decreases. Due to decrease its strength, the elongation of the metal increases, when we apply the load i.e. ductility increases
