To study the effect of removing thermal energy from a system, the student should perform the experiment of cooling a gas and recording its change in state. This experiment will allow the student to observe the direct impact of removing thermal energy from a system by cooling a gas. As the gas loses thermal energy, it will undergo a change in state, possibly transitioning from a gaseous state to a liquid or solid state, depending on the specific gas being studied. By carefully monitoring and recording these changes, the student can analyze the behavior of the gas as thermal energy is removed.
In the case where scientists introduced a genetic code in E. coli bacterium to produce biodiesel when feeding on urban waste, one likely impact could be that the dependence on fossil fuels would decrease. This innovation represents a sustainable and eco-friendly solution to producing biodiesel, a renewable energy source, from urban waste through biological processes. By utilizing bacteria to generate biodiesel from waste materials, there is a potential to reduce the reliance on fossil fuels, which are non-renewable and contribute to environmental issues such as climate change. This approach demonstrates a promising pathway towards promoting sustainability and reducing the carbon footprint associated with traditional fuel sources.
