Question

A light bulb contains 0.0560 g of argon gas with a pressure of 1.34 atm at 26.0 c. The light bulb is then turned on and, after a period of time, the temperature rises to 179c. Calculate the final pressure the light bulb

Answer 1

Answer:

Final pressure of light bulb is 2.03 atm.

Explanation:

Given data:

Initial pressure = 1.34 atm

initial temperature = 26 °C

Finial temperature = 179 °C

Final pressure = ?

Formula:

P1/T1 = P2/T2

Solution:

First of all we will convert the °C into kelvin.

179 +273 = 452 K

26 +273 = 299 K

P2 = P1×T2/T1

P2 = 1.34 atm . 452 K / 299 K

P2 = 605.68 atm/ 299

P2 = 2.03 atm
