Question

At 20 degrees, a gas has a volume of 1.2 litres. What is the volume it occupies at 130 degrees Celsius?

Answer 1

To solve this problem, we can use Charles's law, which states that the volume of an ideal gas is directly proportional to its temperature when pressure is held constant.

Charles's law can be expressed as:

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where:

• $V_1$ is the initial volume of the gas,
• $T_1$ is the initial temperature of the gas,
• $V_2$ is the final volume of the gas (which we need to find),
• $T_2$ is the final temperature of the gas.

Given:

• $V_1=1.2\text{litres}$
• T1=20 °C=20+273.15 KT_1 = 20 , degree ext{C} = 20 + 273.15 , ext{K}T<span class
