### The final temperature of the gas is
.
Explanation
## Step 1: Identify the LawThe problem is about the relationship between the volume and temperature of a gas, which is described by Charles's Law. Charles's Law states that the volume of a gas is directly proportional to its absolute temperature, assuming the pressure remains constant.## Step 2: Use the FormulaTo find the final temperature, we can use the formula:
where
is the initial volume,
is the initial temperature,
is the final volume, and
is the final temperature.## Step 3: Convert Temperature to KelvinGiven that
is the original volume and
is six times the original volume, and
is
, we need to convert this to Kelvin by adding 273.15, which gives:
## Step 4: Substitute Values and SolveSubstituting the given values into the formula, we get:
Solving this equation for
, we get:
## Step 5: Convert Back to CelsiusFinally, we convert this back to Celsius by subtracting 273.15 from
:
which is approximately
