When a ship sinks, the rate of decay and corrosion may be dependent on the final depth of the wreck[/cs_text][/cs_column][/cs_row][/cs_section][cs_section parallax=”false” separator_top_type=”none” separator_top_height=”50px” separator_top_angle_point=”50″ separator_bottom_type=”none” separator_bottom_height=”50px” separator_bottom_angle_point=”50″ style=”margin: 0px;padding: 45px 0px;”][cs_row inner_container=”true” marginless_columns=”false” style=”margin: 0px auto;padding: 0px;”][cs_column fade=”false” fade_animation=”in” fade_animation_offset=”45px” fade_duration=”750″ type=”1/2″ style=”padding: 0px;”][cs_text]Students learn to:
-
outline the effect of:
– temperature
– pressure
on the solubility of gases and salts - identify that gases are normally dissolved in the oceans and compare their concentrations in the oceans to their concentrations in the atmosphere
- compare and explain the solubility of selected gases at increasing depths in the oceans
- predict the effect of low temperatures at great depths on the rate of corrosion of a metal

- perform a first-hand investigation to compare and describe the rate of corrosion of materials in different :
– oxygen concentrations
– temperatures
– salt concentrations - use available evidence to predict the rate of corrosion of a metal wreck at great depths in the oceans and give reasons for the prediction made
