what is the density of water at the bottom of the marianas trench
Mariana Trench At the bottom of the trench the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,000 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%, so that 95 litres of water under the pressure of the Challenger Deep would contain the same mass as 100 litres at the surface. The temperature at the top is 1 to 4 °C (34 to 39 °F).[5]

Mariana Trench The Mariana Trench or Marianas Trench,[1] located in the western Pacific Ocean approximately 200 kilometres (124 mi) east of the Mariana Islands, is the deepest point in the world's oceans. It is a crescent-shaped trough in the Earth's crust averaging about 2,550 km (1,580 mi) long and 69 km (43 mi) wide. The maximum-known depth is 10,994 metres (36,070 ft) (± 40 metres [130 ft]) at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep.[2] However, some, unrepeated, measurements place the deepest portion at 11,034 metres (36,201 ft).[3] For comparison: if Mount Everest were dropped into the trench at this point, its peak would still be over 2 kilometres (1.2 mi) underwater.[a]
Corona Spectroscopy measurements indicate strong ionization and plasma temperature in excess of 1,000,000 kelvins,[1] much hotter than the surface of the Sun.
