Answer:
302 kj heat is released by lowering the temperature
In a phase diagram, the point at which the solid, liquid, and gas coexist simultaneously is called the TRIPLE POINT. There is a specified pressure and temperature at which the substance can exist in equilibrium with these three phases being present.

Answer:
Volume
Explanation:
A cubic centimeters(cm³) is a measure of volume that is equal to a cube with width, length and height are all 1 centimeters. then, multiply length, width and height values together, this will give you the volume of the cube. 1 inch = 2.54 centimeters
Answer:
![\fbox {(2) 4.9}](https://tex.z-dn.net/?f=%5Cfbox%20%7B%282%29%204.9%7D)
Explanation:
Applying the Ideal Gas Equation :
![\boxed {PV = nRT}](https://tex.z-dn.net/?f=%5Cboxed%20%7BPV%20%3D%20nRT%7D)
Finding n :
- n = 64 g / 32 g/mole (<u>Oxygen is diatomic</u>)
- <u>n = 2 moles</u>
Solving for P :
- P = 2 × 0.0831 × 300 / 10 (<u>Temp. should be converted to K</u>)
- P = 60 × 0.0831
- P = 4.9
∴ The pressure inside the flask in bar is 4.9.
