depending on where you live. so if you're in North Carolina it . ( temperature )
According to Albert Einstein's theory of photoelectric effect, metals will only emit electrons when the incident light has a frequency that is above the minimum or threshold frequency.
So if the frequency of the incident light is less than the threshold frequency then electrons will not be emitted from that metal.
The specific heat of the iron can is determined as 0.449 J/g⁰C.
<h3>Specific heat of the iron can</h3>
The specific heat of the iron can is calculated as follows;
Q = mcΔθ
c = Q/mΔθ
where;
- Q is quantity of heat
- Δθ is change in temperature
- m is mass
c = 256/(50 x 11.4)
c = 0.449 J/g⁰C
Thus, the specific heat of the iron can is determined as 0.449 J/g⁰C.

Answer:

Explanation:
Electrolysis is not possible with solid lead (II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes.
The bulb won't glow when the electrodes are embedded in solid lead bromide. The bulb will glow when the material surrounding the electrodes is molten lead bromide. When an ionic compound is in the molten (liquid) form the positive and negative ions are free to move around.
Hopes this Helps :D
