When a 500. gram sample of water at 19.0°C absorbs 8400 Joules of heat, the temperature of the water will change to

Iam not sure butch i thinnk it is ab

Ithink b not to sure hope that : )

The surface of the water droplet is held together by the attraction between molecules. in order for water to flow more easily into these small spaces, you need to decrease its surface tension. you can do this by adding soap, which is a surfactant (a material that decreases the surface tension of a liquid).
