Gasoline burns in the cylinder of an automobile engine. during the combustion reaction, the production of gas forces the piston to move, exerting 560j. also, the engine’s cooling system has to carry away 2.2kj as a result of the increased temperature of the coolant liquid. if the system is defined to be the gasoline and oxygen that react, what is the change in its internal energy?

Explanation:

As we know by first law of thermodynamics that for ideal gas system we have

Heat given = change in internal energy + Work done

so here we will have

Heat given to the system = 2.2 kJ

Q = 2200 J

also we know that work done by the system is given as

so we have

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
