Answer:
The water at 38 °C has faster-moving molecules than the sample at 295 K.
Explanation:
Converting the temperature, 295 K from Kelvin to Celsius:
295 - 273 = 22°C
⇒The boiling point of water is 100°C and its melting point 0°C
⇒When we compare water at those 2 different temperatures ( 22°C and 38°C) we can say that water is in liquid form at both these temperatures as both of them are quite below the boiling temperature and above the melting temperature.
⇒The difference in temperature between water at the 2 given temperatures = 38°C - 22°C = 16°C
Water at 38°C is at a higher temperature and so is warmer than water at a lower temperature of 22°C.
At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Temperature is defined as the measure of the average speed of atoms and molecules. The higher the temperature, the faster these particles of matter move.

Answer:- cell potential = -0.19 volts
Solution:- The equation that shows the connection between 
and cell potential, E is written as:
in this equation, n stands for moles of electrons, E stands for cell potential and F stands for faraday constant and it's value is 
.
It asks to calculate the value of E, so let's rearrange the equation:
Let's plug in the values in it:
since, 
Where C stands for coulombs and V stands for volts.
So, 
E = -0.19 V
So, the cell potential is -0.19 volts.
