I . An adiabatic system consisting of a thermally insulated reaction vessel with a 10 R resistance heater inside is connected to a 20 V

power supply, which is switched on for 50 s.

(i) Analyse the change in internal energy AU of the system.

(ii) Repeat the analysis for an isothermd diuthermic system (i. e. the

system is in contact with a thermal reservoir such as a water bath).

answer is  

loa ≅ lma

to prove that the triangles are congruent using the aas congruence

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
