Which scenario shows responsible behavior with regard to lab safety? 1. nathan threw out his lab safety instructional manual after reading it. 2. jessica and elizabeth ate their lunch and evening snacks in the lab area. 3. haley poured multiple tubes of poisonous chemicals down the lab sink. 4. adam immediately cleaned up the fluids he had spilled in the lab area. (earth science)

The answer would be:

Adam immediately cleaned up the fluid he had spilled in the lab area (option 4)

This is why:

If there is a spill in the lab, you should clean it, but also do not forget to also follow the safety precautions, especially with chemical spills. Spills can cause injury, like someone might slip on it or you might slip on it. It will also prevent contamination of other chemicals. Some chemicals can become volatile when mixed with other substances.

As for the other options. You should keep the manual even after reading as reference. NEVER eat in the lab. You may never know what you might ingest as well. All chemicals have guidelines when it comes to disposal. Never throw them all down the sink.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
