Question

A gas at 5.00 atm pressure was stored in a tank during the winter at 5.0 °C. During the summer, the temperature in the storage area reached 40.0 °C. What was the pressure in the gas tank then? A gas at 5.00 atm pressure was stored in a tank during the winter at 5.0 °C. During the summer, the temperature in the storage area reached 40.0 °C. What was the pressure in the gas tank then? a) 5.63 atm b) 4.44 atm c) 69.5 atm d) 0.625 atm e) 40.0 atm.

Answer 1

a) 5.63 atm

Step-by-step explanation:

We can use combined gas law

The combined gas law combines the three gas laws:

• Boyle's Law, (P₁V₁ =P₂V₂)
• Charles' Law (V₁/T₁ =V₂/T₂)
• Gay-Lussac's Law. (P₁/T₁ =P₂/T₂)

It states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.

P₁V₁/T₁ =P₂V₂/T₂

where P = Pressure, T = Absolute temperature, V = Volume occupied

The volume of the system remains constant,

So, P₁/T₁ =P₂/T₂

a)
`(5)/(278) =(P_2)/(313)  \\\\P_2=(5*313)/(278)\\ P_2 = 5.63 atm`
