A gas is initially at 15 °C at 6 atm and occupies 49 liters. What will its new volume be if its temperature increases to 87 °C and its
pressure is dropped to 2 atm? Round your answer to the nearest liter.

Answer 1

There are many ways to solve this question .We will use Temperature

• T_1=15°C=288K
• T_2=87°C=360K
• V_1=49L

Using charles law

$\\ \sf\longmapsto \dfrac{V_1}{V_2}=\dfrac{T_1}{T_2}$

$\\ \sf\longmapsto V_2=\dfrac{V_1T_2}{T_1}$

$\\ \sf\longmapsto V_2=\dfrac{49(360)}{288}$

$\\ \sf\longmapsto V_2=\dfrac{17640}{288}$

$\\ \sf\longmapsto V_2=61.25L$
