Her hypothesis is wrong. <span>Increased </span>temperature<span> causes an increase in kinetic energy. The higher kinetic energy causes more motion in the </span>gas<span> molecules which break intermolecular bonds and escape from solution. Check out the graph below: As the </span>temperature<span> increases, the </span>solubility<span>of a </span>gas<span> decreases</span>
In terms of function, bird wings are used to flap transversely, whereas butterfly wings are used to flap laterally. In terms of structure, bird wings are filled with hollow bones for easier flight, whereas butterfly wings are structured by scales and tiny hairs.
