A) increases
B) decreases
C) remains unchanged
D) may increase or decrease depends on size
Correct Answer: A
Solution :
The influence of temperature on surface tension\[(\gamma )\]is given by \[_{\gamma }{{V}^{2/3}}=k({{T}_{C}}-T)\]where V is molar volume of that substance,\[{{T}_{C}}\] is critical temperature, k is constant. Since, temperature is directly proportional to\[{{V}^{2/3}}\]. Since, volume of big drop increases its temperature also increases.You need to login to perform this action.
