The SI base unit for length is meter.
In order to make smaller measurements, you can use the centi-, milli-, micro-, etc. prefixes.
When you want to reference larger measurements, you can use the kilo-, mega-, giga- and prefixes such as those.
Answer:
solid has definite shape and volume.
liquid do not have definite shape but have definite volume.
gas do not have definite shape and definite volume.
solid have lowest compressibility out of three, liquid have more compressibility than solid but less than gases. gases have the highest compressibility out of three. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
Answer: 0.529 atm
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
![\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1V_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2V_2%7D%7BT_2%7D)
where,
= initial pressure of gas = 0.998 atm
= final pressure of gas = ?
= initial volume of gas = 2 L
= final volume of gas = 3.5 L
= initial temperature of gas = ![34.0^oC=273+34.0=307.0K](https://tex.z-dn.net/?f=34.0%5EoC%3D273%2B34.0%3D307.0K)
= final temperature of gas = ![12.0^oC=273+12.0=285.0K](https://tex.z-dn.net/?f=12.0%5EoC%3D273%2B12.0%3D285.0K)
Now put all the given values in the above equation, we get:
![\frac{0.998\times 2}{307.0K}=\frac{P_2\times 3.5}{285.0K}](https://tex.z-dn.net/?f=%5Cfrac%7B0.998%5Ctimes%202%7D%7B307.0K%7D%3D%5Cfrac%7BP_2%5Ctimes%203.5%7D%7B285.0K%7D)
![P_2=0.529atm](https://tex.z-dn.net/?f=P_2%3D0.529atm)
Thus the pressure if it is brought to a higher altitude where it now occupies 3.5 L and is at 12.0 °C is 0.529 atm
