If the pressure of each gas is increased at constant temp until condensation occurs, which gas will condense at the lowest pressure?

there are 3 gases: methane, ethane, and butane. (formula, molar mass, temperature, and pressure given)

Butane

Explanation:

The only inter molecular attractions present between hydrocarbons is weak london dispersion forces. These forces are size dependent. More the surface area more the attractions.

Out of given gases butane is the highest member with greatest surface area among methane, ethane and itself.

So it will have higher intermoelcular london dispersion forces.

This makes it to condense easily at lower pressure as compared to methane and ethane.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

1. they vary with a higher number because boiling is way hotter than melting
