Freezing the substance and condensing it will not increase the entropy of a substance. In fact, dissolving the substance into water is the only way to increase the entropy of a certain substance. The entropy increases because it diversify with each other.

tigry1 [53]

Answer:

A. The increase in size of the battery results in a smaller internal resistance and hence, a larger current delivery.

B. Zinc serves as the anode

Explanation:

A. The current that a battery can deliver is affected by the internal resistance of the battery.

The internal resistance resistance, r, is the resistance to flow of current within the battery. The smaller the internal resistance for a given emf, the more current and the more power the source can supply.

The relationship between current, I, emf, E, the external load ,R, and internal resistance is given by the equation:

I = E / (R + r)

The bigger the size of a battery, the smaller its internal resistance and thus, the larger the current the battery can deliver.

B. In a battery, the cathode is reduced by accepting electrons from the anode, while the anode is oxidized to zinc ion by giving up its electrons to the cathode.

From the equation of the reaction, metallic zinc is oxidized by giving up two electron to the cathode.

Zn(s) ----> Zn2+ + 2e-

Therefore, metallic zinc serves as the anode.

xenn [34]

Answer

Manual samplers are prone to effects of temperature, speed of wind and air concentrations.

Explanation

Manual samplers face several challenges that can act as drawbacks to obtaining accurate results. They are subjected to effects of sampling duration where long sampling times are needed to obtain adequate mass for detection. Manual samplers face challenges when measuring non-volatile species because particles are observed into the adsorption medium at a slower rate of diffusion.
