Benzene
- Benzene has low density than the water itself of about 0.9 g/cm³
Low denisty object than the water usually <u>floats on the water</u>.
Another example: orange peel which floats on water has density of about 0.84 g/cm³
H- is the one without electron
A semiconductor's resistivity decreases with the increase in temperature.
More is the heat imparted to it, it will behave more as an insulator.
