Simon Yoon Posted January 28, 2016 Report Share Posted January 28, 2016 I am doing my Physics HL IA on "how does the mass of impurity added affect the surface tension of water?"It did work and I got the results but I am actually worried whether it is relevant to physics. I could try to explain the theory behind it in terms of physics by mentioning intermolecular forces, cohesion... etc. and not talking about chemistry. Yet I am quite worried if the concept is more like chemistry. Although my teacher approved and advised to just explain the concept in terms of physics I am not too sure. Could anyone tell me if it is fine to continue with this topic? thanks Reply Link to post Share on other sites More sharing options...
Sandy Posted February 4, 2016 Report Share Posted February 4, 2016 Hey Simon, The topic looks good, and its unique. As long as you're not going too much into the chemistry part (intermolecular forces, yield, etc) its cool. Just stick to the physics aspect of everything you're including. The concept comes under both physics and chemistry so there's nothing to worry about there. Good luck with your IA! Reply Link to post Share on other sites More sharing options...

You should definitely use the precise terms (intermolecular forces), but an emphasis should be on physics concepts (electrostatics, dipoles etc).
