NEED HEL Betty while doing an underwater experiment is tasked with determining the buoyancy of a research balloon at test depth. The balloon is initially inflated with 40.0 L of air at sea level (1.00 atm and 25.0⁰C) and sinks in the water to where the pressure is 11.0 atm and 4.0⁰C. She used the combined gas law to calculate that the final volume will be 3.38 L of air.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
