No they do not measure the same.
Surface tension is a property of the surface of a liquid that allows it to resist an external force. It is revealed, for example,
<span>in floating of some objects on the surface of water, even though they are denser than water, and in the ability of some </span>
<span>insects (e.g. water striders) and even reptiles (basilisk) to run on the water surface. This property is caused by cohesion </span>

<u>Answer:</u> The volume of given mas of tin block at STP is 
<u>Explanation:</u>
To calculate volume of of the substance, we use the equation:
We are given:
Mass of tin = 95.04 g
Density of tin = 
Putting values in above equation, we get:
Hence, the volume of given mas of tin block at STP is
