Compared to a sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure A) condenses to a liquid. B) is more soluble in water C) forms diatomic molecules. D) behaves more like an ideal gas

Option D is correct.

Explanation:

Compared to a sample of helium at STP, the same sample of helium at a higher temperature and a lower pressure because any gas at a higher temperature and a lower pressure will  behaves like  an ideal gas. for eg.

nitrogen at STP show its behavior as an ideal gas.

When pressure of a gas increased & temperature is decreased then the gas does not follow ideal gas law.

Therefore option D is correct.

i think so it’s will be b yes i believe its

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
