All molecules are made up of:
a)hydrogen
b)minerals
c)atoms
d)gas

The only answer you can pick from that group is atoms, but it is a shaky answer. It's just that nothing else is appropriate. Hydrogen won't work C-Cl4 is a molecule. No hydrogen.

Minerals. Again CCl4 does not contain any minerals.

Gas: Doesn't work. Many things (perhaps even the majority of compounds) are not gaseous. For example NaCl is table salt. It's a solid

Choose C. Ions are what make me hesitant.

elements make up everything, and they combine to make compounds.

the answer is c

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
