When water molecules stick to something other than water, we call this
What is adhesion

All organic molecules contain which element(s)?
What is Carbon because many organic molecules also contain hydrogen, but not all of them. Carbon is the true defining atom of an organic molecule because it makes up the ‘skeleton’ of the organic molecule.

True or false: A scientific theory is merely a tentative explanation subject to testing and modification.
What is False (Remember that hypotheses are tentative explanations. A theory is well established and supported. Does that mean that a theory cannot be rejected? It can, but it would require rejecting all of the hypotheses that support it first. Good science is always falsifiable!)
