A piston compresses the air in the cylinder by doing 67.0 J of work on the air. As a result, the air gives off 149.0 J of heat to the surroundings. If the system is the air in the cylinder, what is the change in its internal energy?

The human activities in two locations are described below: location a: rampant use of plastic containers location b: excessive use of pesticides and fertilizers which statement is most likely true? location a will have poor air quality because plastic is biodegradable. location a will experience water scarcity because plastic absorbs moisture. the population of honeybees will increase in location b because production of crops will increase. the population of fish in location b will decrease because the water is contaminated.
