3. A large bubble (5 m3) of pure methane gas is released from a broken riser pipe on an\ offshore oil rig. If the break in the riser pipe is 600 m beneath the ocean surface where the\ water temperature is 7 C, how big is the methane bubble when it reaches the floating oil rig at\ the surface where the temperature is 30C? Draw a simple sketch of state 1 and state 2 and\ carefully define your variables.
