Because the only force holding methyl substituted butane together is a very weak dispersion force and it is not very heavy so it pretty much wants to be a gas.
Butane has higher melting and boiling points.
The melting and boiling points are different. Butane has a melting point of 135.4K and 2-methylpropane [isobutane] has a melting point of 114K. The boiling point of Butane is 272.6K and isobutane @ 261K. It has to do with there structures. J
n-butane : Melting point −138.4 °C (135.4 K), boiling at −0.5 °C (272.6 K)iso-butane (methylpropane): Melting point -159.6 °C, (114 K) , boiling at -11.7 °C, (261 K)
benzene has lower boiling point than water
Butane has a boiling point of 0.5 degrees centigrade
The boiling point of butane is roughly -1.1oC.
because of difference in structure propane (C3H8) has bigger molar mass then butane (C4H10) the molecules of butane are heavier and the forces between them are stronger as in propane, because of this more energy is needed to transfer liquid butane to gas
Butane because it contains more atoms and is heavier.

Because its Boiling point is closer to normal room temperature.
The boiling point of Butane is approximately -0.5 C at sea level (This boiling point will drop with an increase in altitude given the reduced pressure). This means that as the lighter nears freezing less gas will be vaporized inside of the lighter and will make it hard to light.
