The joule (j) is a unit of energy. recall that energy may be converted between many different forms such as mechanical energy, thermal energy (heat), chemical energy, electrical energy, and light. the mechanical energy produced by a system is called work. when work is accomplished through the changing volume of a gas, it is called pv work and is given by the formula w=−pδv, where w is the work, p is the external pressure, and δv is the change in volume. if the volume change and pressure are in liters and atmospheres respectively, then the work will have units of liter-atmospheres, which can be converted to joules using the conversion factor 1 l⋅atm=101.3 j. work can also be expressed as force multiplied by distance: w=f×d, where w is the work in joules, f is the force in newtons, and d is the distance in meters. note that 1 n⋅m=1 j. a piston has an external pressure of 11.0 \rm atm. how much work has been done if the cylinder goes from a volume of 0.170 liters to 0.460 liters.
express your answer in joules.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
