I took a test like this and my teacher said this was right so ye. hopefully I remembered correctly if its wrong im sorry ;C
Answer:
What is surface tension?...Surface tension is the surface of film of any kind of liquid caused by attraction of the particles in its surface layer. This bulk of liquid is something that tends to minimize surface areas.
Answer:
The thermal efficiency of an engine is
that is 15%
Explanation:
Specific heat of a gas at constant volume is
![C_{v}=\frac{fR}{2}](https://tex.z-dn.net/?f=C_%7Bv%7D%3D%5Cfrac%7BfR%7D%7B2%7D)
here,
degree of freedom
universal gas constant
Thermal efficiency of a cycle is
![\frac{total workdone}{gross heat absorbed}](https://tex.z-dn.net/?f=%5Cfrac%7Btotal%20workdone%7D%7Bgross%20heat%20absorbed%7D)
Gross heat absorbed is amount of heat that absorbed.
