4. In the simulation shown below, each insulated beaver contains equal amounts of the same fluid. The starting temperature of beaker A was 1000 C and the starting temperature of beaker B was 00'C Assuming no heat is lost, what is the best estimate of the temperatures of each beaker at 10 minutes?

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.
