Question & Answer
Choose the Best Answer
The photoelectric effect shows that light can be absorbed and emitted by electrons, which gain energy from heat.
Black-body radiation indicates that all objects emit light based on their temperature.
The Bohr model suggests that electrons gain energy in discrete amounts, which isn't affected by temperature.
Classical mechanics predicts that increasing temperature causes all particles to emit energy uniformly.
Understanding the Answer
Let's break down why this is correct
When a metal is hotter, its atoms vibrate faster. Other options are incorrect because The photoelectric effect happens when light knocks electrons out of metal, but it does not tell us how temperature changes the light’s energy; The Bohr model describes electrons in fixed shells, but those shells stay the same when the metal warms.
