A scuba diver takes a tank of air on a deep dive. The tank’s volume is 10 L and it is completely filled with air at an absolute pressure of 232atm at the start of the dive. The air temperature at the surface is and the diver ends up in deep water at 60 oF. Assuming thermal equilibrium and neglecting air loss, determine the absolute internal pressure of the air when it is cold.
Answer to relevant Questions(a) If the temperature of an ideal gas increases and its volume decreases, will the pressure of the gas (1) increase, (2) remain the same, or (3) decrease? Why? (b) The Kelvin temperature of an ideal gas is doubled and its ...A steel beam 10 m long is installed in a structure at 20 oC. What is the beam’s change in length when the temperature reaches (a) – 25 oC and (b) 45 oC? Apiece of copper tubing used in plumbing has a length of 60.0 cm and an inner diameter of 1.50 cm at 20 oC. When hot water at flows through the tube, what are (a) The tube’s new length and (b) The change in its ...The coldest inhabited village in the world is Oymyakon, a town located in eastern Siberia, where it gets as cold as – 94 oF. What is this temperature on the Celsius scale? (a) Estimate the total amount of translational kinetic energy in a small classroom at normal room temperature. Assume the room measures 4.00 m by 10.0 m by 3.00 m. (b) If this energy were all harnessed, how high would it be ...
