Isaac pours water into
one container and liquid acetone into another
he seals both containers. he measures the
gas pressure above both liquids. at the same
temperature, the pressure of the acetone gas
is higher than the pressure of water vapor
which liquid requires more thermal energy to
change from a liquid to a gas? explain.

the answer would be c

i believe the answer is a.

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
