If a bottle of oxygen with a pressure of 500 kPa with a volume of .30 L at 290 K has a temperature change to 370 K and the volume changed to 1.5 L because the bottle broke open and leaked into the bottles outer container, then what is the new Pressure of the oxygen? Remember the combined gas law equation. P1V1 / T1 = P2V2 / T2

a
.128 kPa
b
128 kPa
c
0 kPa
d
500 kPa Lp

Apair of 10μf capacitors in a high-power laser are charged to 1.7 kv.a. what charge is stored in each capacitor? b. how much energy is stored in each capacitor?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.

The pilot of a helicopter hovers at an altitude of 1200 feet over a park. the angle of depression to the base of a statue is 17 degrees. the angle of depression to the nearest park exit, in line with the statue, is 14 degrees. to the nearest foot, what is the distance from the statue to the exit?
