Q = C.v
v = Q/C
v = 4 × 10^(-10)/250
= 4 × 10^(-10)/2.5 × 10^2
= 1.6 × 10^(-12) volt
First law is Conservation of Energy
Second is that entropy of an isolated system will always increase with time.
Entropy is the change of disorder through time. The best statement which relates to the 2nd law is C. Thermal energy flows from areas of higher to lower temperature
No
Explanation:
Tap water will not boil and freeze at those exact temperature which are the boiling and freezing points.
O°C and 100°C are the boiling points of pure water.
Pure water is a pure substance with a definite composition made up of 2 atoms of hydrogen and 1 atom of oxygen.
Pure water boils at 100°C and freezes at O°C ,
- Tap water is not pure water.
- It has some impurities in it which causes causes the elevation of the boiling point of liquids and widening of the boiling range.
- Tap water is treated water that contains some other dissolved chemicals.
