<h3>Answer:</h3>

3.313 × 10^-34 Joules

<h3>Explanation:</h3>

The frequency of a photon is 0.5 Hz

Required to find the energy of a photon;

We need to use the formula for energy of a photon;

Energy,E=hf, where h is the plank's constant and f is the frequency of the photon.

Plank's constant, h = 6.626 × 10^-34 J-s

Therefore;

Energy =  6.626 × 10^-34 J-s × 0.5 Hz

            = 3.313 × 10^-34 Joules

Thus, the energy of a photon with a frequency of 0.5 is 3.313 × 10^-34 Joules

A piece of iron (C=0.449 J/g°C) and a piece of gold (C=0.128 J/g°C) have identical masses. If the iron has an initial temperatur
spin [16.1K]

Answer:

The correct answer is B. Since the two metals have the same mass, but the specific heat capacity of iron is much greater than that of gold, the final temperature of the two metals will be closer to 498 K than to 298 K

Explanation:

Iron is hotter and gold is colder, therefore, according to laws of thermodynamics, iron will lose heat to gold until they are at the same temperature.

The specific heat capacity of iron(0.449) is over three times that of gold(0.128). Since masses are equal, this means that each time iron's temperature drops by one degree, the energy released it releases makes gold's temperature increase by more than 3 degrees. So gold's temperature will be climbing much faster than iron's is falling. Meaning they will meet closer to the initial temperature of iron than that of gold
