An LDR's resistance changes with light intensity, while a thermistor's resistancce changes with temperature.
In dark, LDR's resistance is large and in the day/light LDR's resistance is small.
At low temperature, thermistor's resistance is large, while at large temperature it resistance is small.
In an LDR Resistance increases as light intensity falls, while in a thermistor resistance falls as temperature falls.
It is probably gas as pure water starts boiling at 100d degrees C
The answer that fits the blank is SOURCE REDUCTION. Source reduction refers to the prevention of further pollution by eliminating the source before this can produce the wastes. This helps in the reduction of pollution, thus reduces the amount of toxins brought by these wastes that may harm the environment.
0.008hertz is the correct answer
