Which temperature is required for the cell potential to be the standard cell potential?
a. 100°c
b. 25°c
c. 0°c
d. –273°c

The answer is B. 25°C.

A temperature of 25°C can be considered as a room temperature. It is an optimal temperature for the most living beings which cell potential is considered as standard. It is known that at 100°C water boils, so this temperature cannot be standard, cells will degrade at this temperature. Similarly 0°C and –273°C are too cold, water of the cells will freeze, cells will freeze, and cell potential will not be optimal.

They formed the oceans.  as they melted water was formed and the water made the oceans
