What pressure must be used to compress 850 mL of argon gas at 146 kPa to 150 mL? (Temperature is held constant.)
It can be a solid liquid or a gas, depending on the temperature
The number of atoms per cubic centimeter of argon depends on the density of the argon gas or material. Pure gaseous argon at standard temperature and pressure (STP) has a density of 1.784 grams per liter, which is equivalent to approximately 2.920 x 10^19 atoms per cubic centimeter. However, the density of solid or liquid argon may be different, and it can vary based on temperature and pressure.
the freezing temperature of Argon is-189 celsius.(melting)
There is no such thing as "27.9 of argon". You must specify the unit, such as moles, kilograms, etc. The same applies to the pressure and the temperature - the unit must be specified, since there are several options in each case. Once you know that, use the formula for the universal gas law to calculate the corresponding volume.
Most of the time when you encounter argon and nitrogen they will be gasses. Until you get up to high pressures, they will both behave more or less like ideal gasses. For an ideal gas, the volumetric thermal expansivity (i.e. relative change in volume due to temperature change) is: ßp = 1/T where p denotes a constant pressure process. The coefficient of linear expansion can be calculated from this to get: α ≈ ßp/3 For liquids, the value has to be measured because it certainly isn't an ideal gas when it is liquid! For liquid argon, the coefficient of thermal expansion is reported to be 0.01113 1/°C. For liquid nitrogen, the coefficient of thermal expansion is reported to be 0.00753 1/°C Note that you have to get down to cryogenic temperatures to liquefy argon and nitrogen and it tends to be under pressure when stored in a closed vessel.
that depends on the temperature and pressure, at room temperature and pressure argon is a gas
Argon is a gas at room temperature. It is in the noble gases on the Periodic Table.
At normal temperature and pressure it is a gas.
It can be a solid liquid or a gas, depending on the temperature
The answer will depend on the pressure and temperature.
At normal temperature and pressure, it is a gas.
The question cannot be answered because there are no units given for the pressure not temperature.
At room temperature and normal atmospheric pressure it is a gas.
They are all gases at normal temperature and pressure.

The answer depends on the temperature and pressure.
Depends entirely upon pressure. At one atmosphere, Ar liquifies at -186C
