Answer
### 15.0 atm
Explanation
## Step 1: Identify the initial conditions### The initial pressure (
) is 10 atm and the initial temperature (
) is 300 K.## Step 2: Identify the final temperature### The final temperature (
) is 450 K.## Step 3: Apply the ideal gas law### According to the ideal gas law, for a constant volume, the pressure and temperature are related by
.## Step 4: Solve for the final pressure (
)### Rearrange the formula to
.### Substitute the known values:
.### Calculate the result:
.## Step 5: Round to the nearest tenth### The final pressure rounded to the nearest tenth is 15.0 atm.
