A copper block (20°C) is placed in contact with a lead block (30°C), which is already in contact with an iron block (70°C).
What will happen in this situation?
Heat will flow from the iron to the lead and from the lead to the copper until the temperatures are equal.
Heat will flow from the copper to the lead and from the iron to the lead until the temperatures are equal.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
