The surface tension of most of the liquids decreases with a rise in:

The property utilized in the manufacture of lead shots is

$A$ soap film of surface tension $3 \times 10^{-2} \, N/m$ is formed in a rectangular frame and can support a straw. The length of the film is $10 \, cm$. The mass of the straw the film can support is ........ $g$.

In most liquids, with a rise in temperature, the surface tension of the liquid

If a section of a soap bubble (of radius $R$) through its center is considered, then the force on one half due to surface tension is

Explain why is hot soup more tasty than the colder one?
