Question

When fluorohalides luminesce, they release all their energy as light.

a) True
b) False

Answer 1

False. When fluorohalides luminesce, they release energy as light, but not all of their energy. Some energy is released as heat.

Step-by-step explanation:

False. When fluorohalides luminesce, they release energy as light, but not all of their energy. Some energy is released as heat. Fluorohalides are fluorescent compounds that emit light as their excited electrons return to the ground state. This phenomenon is commonly observed in fluorescent lights, where electrical energy excites electrons in molecules coating the bulb's interior, and as these electrons return to the ground state, they fluoresce, producing light.
