So this is a true or false question.
00:02
So let's start from number one.
00:04
So if a liquid has a strong imfa, it has low surface tension.
00:10
So what is imfa? this stands for intermolecular force of attraction.
00:22
Attraction.
00:26
So i, m, f, and a.
00:29
So obviously when you have a higher attraction and those intermolecular force is greater and then they keep the molecule together.
00:41
So higher i or stronger i, m, f, a obviously means that you have a high surface tension.
00:52
The tension keep the molecule together.
00:55
The original statement says it's lower surface tension, so this is the wrong statement.
01:04
So this is a f statement.
01:13
Second, for liquid, viscosity decreases with decreasing temperature.
01:22
Decreasing temp cause decreasing viscosity...
