7.63 7.64 7.65 52 Underwater pressure increases by 14.7 psi for every 10 m of depth. Standing on a boat in scuba gear, you fill a balloon with helium. a. If you take the balloon with you as you dive to a depth of 40 m, what, if anything, will happen to the size of the balloon (assume temperature stays the same)? b. If the balloon slips out of your hand and floats upward before you dive, what, if...

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...

5. Would you expect the volume of gas contained in a balloon to increase or decrease if it is exposed to lower temperatures? A balloon containing 3.50 L of gas at room temperature, 20 °C, is submerged into a vat of liquid nitrogen. The temperature of liquid nitrogen is 77 K. What will be the volume of the balloon at this very cold temperature? 6. A sample of CO2 gas occupies a volume of 225 mL at 25°C. If the...

answer asap please
A sealed balloon is filled with air at atmospheric pressure (P = 1.01 X 105 Pa) at 30°C (typical conditions for the surface of the Earth in St. Thomas). You take the (sealed) balloon with you on top of Mountain Top, which has an elevation of about 450m, where the average air pressure is 9.6 x 109 Pa. The temperature at the top is 26°C, a bit cooler. 2.5 pts. - a) How big is the balloon...
