Whatever it is being heated by has a certain temperature and once the water teaches that equivalent temperature it cannot go higher or lower unless its heat source does too
The temperature<span> remains constant during these phase transitions. </span>Water<span> has a high </span>boiling<span> point because of the strong hydrogen bonds between the </span>water<span> molecules; it is both a strong hydrogen bond donor and acceptor. The first change of phase is melting, during which the </span>temperature stays the same while water<span> melts.</span>
