Answer:

Molality does not change with temperature.

Explanation:

Mass is completely independent of temperature; molality is given by

#"molality" = "mol solute"/"kg solvent"#

The number of moles of the solute also does not change with temperature, since moles is determined directly from mass.

With this in mind, molality does not change with temperature, because molality itself is determined from the mass of the solution components.
