Afixed amount of ideal gas is held in a rigid container that expands negligibly when heated. at 20°c the gas pressure is p. if we add enough heat to increase the temperature from 20°c to 40°c, the pressure will be:
a. equal to 2p
b. less than 2p
c. impossible to determine since we do not know the number of moles of gas in the container
d. greater than 2p
or
e. impossible to determine since we do not know the volume of gas in the container.

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.
