When Ice melts why does the temperature stay at zero  for a while before increasing ? 

• The particles must all reach the same temperature before the temperature can change.
• The hot plate wasn't turned on.
• The thermometer was not connected correctly.
• The kinetic energy was too high and the particles had to slow down.
