Question

help! please answer #2 and graph the data. ( v stands for volume in question 2)

How does the pressure of the gas change with Temperature? The pressure of gas increases when the temperature of the gas Sincveased. 2. What product or ratio of properties remains constant (PxT, PXV, TXV, P/V, V/T, etc)? When you have decided, calculate the constant for the first data point. For this calculations you need to use Kelving Temperatures! Make sure to show calculations including units. 3. Discuss how the average speed of the particles change and explain the reasons for that. it happens when theres an increase of temperature, the partles gain kinetic energy and move faster. I think it depends on the weight of the particle as well. Heavien particles move more slowly than the lighter ones at the same temperaturel 4. If a sample of gas in a container of fixed volume is initially at 26.3°C and 652.5 torr, what will its pressure be if the Temperature in increased to 52.6°C? 10 652.tor (T2):52, 6C 652.5 ton P₂ 709.8tom (T) = 2.6.3°C (52.6+273)k . 299. 325.6k (P2)?

Answer 1

Various gas laws are used to express the constant parameters.

The following are the parameters used to remains constant,

According to Boyle's law, Pressure is inversely proportional to volume (assuming Temperature (T) and Amount of gas(n) remains constant).

P x v = constant

According to Charle's law, Volume and temperature are directly proportional to each other (assuming Pressure (P) and Amount of Gas(n) remain constant)

$\frac{V}{T} = Constant$

According to Gay-Lussac's law, Pressure and temperature are directly proportional to each other (assuming Volume (V) and Amount of Gas(n) remain constant)

$\frac{P}{T} = Constant$

Here, data points were given only to prove Gay-Lussac's law, i.e., P/T = constant. (Temperature is substituted in units of K).

For the first data point,

$\frac{P}{T} = \frac{1.3}{73} = 0.0178\simeq 0.02$

For second data point,

P 2.5 T = 103 = 0.02

For third data point,

$\frac{P}{T} = \frac{3.5}{173} = 0.02$

Likewise, it will remain same for all the data points.

The graph for the data is given below.
