A 3L sample of an ideal gas at 178 K has a pressure of 0.3 atm. Assuming that the volume is constant, what is the approximate pr
harina [27]

Answer: The approximate pressure of the gas after it is heated to 278 K is 0.468 atm.

Explanation:

Given: T_{1} = 178 K,      P_{1} = 0.3 atm

T_{2} = 278 K,           P_{2} = ?

According to Gay Lussac law, at constant volume the pressure of a gas is directly proportional to the temperature.

Formula used to calculate the pressure is as follows.

\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\

Substitute the values into above formula is as follows.

\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\\frac{0.3 atm}{178 K} = \frac{P_{2}}{278 K}\\P_{2} = 0.468 atm

Thus, we can conclude that the approximate pressure of the gas after it is heated to 278 K is 0.468 atm.
