Item 10 ® 10 of 13 10 of 13 ~ Constants | Periodic Table A scuba tank is filled with air to a pressure of 261 atm when the air temperature is 29°C. A diver then jumps into the ocean and, after a short time treading water on the ocean surface, checks the tank's pressure and finds that it is only 251 atm. Part A Assuming the diver has inhaled a negligible amount of air from the tank, what is the temperature of the ocean water? Express your answer using two significant figures. O AS o 2 ?
