The heat transferred to the ice increases the thermal energy of the molecules of water. Why does this cause a change in state?

It creates a change in state because the heat starts to slowly melt the ice.

Explanation:

I took a test.

As energy is transferred to the water molecules in the ice, the motion of the molecules increases. The motion of the molecules increases enough that it overcomes the attractions the water molecules have for each other causing the ice to melt.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
