Incandescent bulbs work by conducting an electric current along a filament made of a long, thin piece of tungsten metal. The filament must be heated to temperatures of about 2,300 degrees Celsius to glow and emit a white-hot light. But the process transforms only 5 percent to 10 percent of the electricity used into visible light. The rest is transformed into heat, which can eventually increase the temperature of a room.
CFL bulbs, on the other hand, are made of glass tubes filled with gas and a small amount of mercury. The amount is so small that an old-fashioned glass thermometer holds 100 times as much mercury as one CFL bulb. Light is emitted when mercury molecules in a CLF bulb become excited by electricity running between two electrodes at its base. The mercury emits an invisible ultraviolet light that becomes visible when it hits the white coating inside the CFL bulb.
Basically, based on how they both work, fluorescent bulbs last longer and do not release as much heat as incandescent bulbs which means it's also better for the environment.
It would be B. Because every angle has to add up to 180 degrees. 180-70 would give you 110
Going to walk my dog I will help when I get back lol
Answer:
They have no freedom to move
Explanation:
Particles can be solids, liquids and gases.
Solids are the substances in which the atoms are very close to each other. It is very difficult to separate the molecules. The atoms cannot move from one place to another. The inter molecular forces between them is very strong.
Hence, the correct option that describes the movement of atoms in a solid is (c) "They have no freedom to move".
