How does the modulus of elasticity change with temperature?
It decreases with increase in temperature
It increases with increase in temperature
It sometimes increases, sometimes decreases with increase in temperature
It does not depend on temperature
The modulus of elasticity decreases with increase in temperature.
Normally, solubility of a crystalline solid increase with temperature. Does it increase uniformly in all cases ? Name a substance whose solubility :
(a) increase rapidly withe temperature.
(b) increase gradually with temperature.
(c) increase slightly with temperature.
(d) initially increases then decreases with rise in temperature.
Why does solubility of gases increase with decrease in temperature?
