A 100 watt light bulb draws a little less than one amp. A refrigerator draws much more when compressor is running. The duty cycle of the light and refrigerator will ultimately determine which uses more power on a Kilowatt Hour basis.

yes
Refrigerator- it takes more power to kick on and it pulls more electricity than a light bulb
It uses modern technology to give better efficiency. A filament bulb has an incandescent (hot) piece of tungsten wire, which produces light but also heat. A fluorescent bulb uses a different process to produce more light and less heat.
Less than 0.02 watt/hours. Running your 100w bulb for an hour uses 100 watt/hours. The inrush current during the cold resistance of the bulb lasts for only a millisecond before the bulb is hot. This is insignificant on your electric bill even if you sat and flicked the lightswitch for the whole month, and is a common misconception that someone who didn't know what they were talking about made up.

electricity because a light bulb needs electricity
if there a light fixture under the floor (on the ceiling of the room underneath) the heat will eventually rise. this is most frequent when there is an incandesent light fixture in an uninsulated floor (like a basement 100w light bulb is left on) something like 90% of electricity used by a 100w bulb is heat.

Very little ! About the same as an ordinary 100W light-bulb. Most of the time, it's just sat there in 'stand-by mode' waiting for someone to insert their card.
no
Electricity + Glass = Light bulb
