Cho mạch điện có sơ đồ như hình 11.4, trong đó các ắc quy có suất điện động E1 = 12V; E2 = 6V và có điện trở không đáng kể. Các điện trở R1 = 4Ω; R2 = 8Ω

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?
