troposphere
Explanation:
The troposphere is the temperature zone of the atmosphere where most precipitation occurs. It has a normal temperature of 0 degrees Celsius. This layer is where the majority of weather events take place. It is 10–15 kilometers thick above the Earth's surface.
Electrical conductivity tester.
If the bulb begins to glow brightly when the plug is submerged in the unknown solution then the solution has high conductivity.
The bright glow of the bulb resulting from the experiment indicates that the current flows easily through the unknown liquid.
