Answer:
2 Atm; 2.016 g
Explanation:
Changing the volume without changing the temperature or mass only changes the pressure. Volume and pressure are inversely proportional so halving the volume will double the pressure.
P = 1 Atm, T = 0 °C are "standard" temperature and pressure (STP). The volume of 1 mole of gas is 22.4 L under these conditions. That means the amount of hydrogen gas in the cylinder is 1 mole, so has a mass of 2.016 g.
After the volume reduction, the pressure is 2 Atm, and the mass remains 2.016 g.
The answer with this question you could use the characteristic properties you could say it’s a liquid or the substance in the fluid state of matter having no fixed shape but a fixed volume the example would be water. Solid gas you can include melting point boiling point whether it’s an element or a pure substance.
Answer:
Boyle's Law
Explanation:
- This law states volume and pressure have an inverse relationship when temperature is constant.
