Question
The volume of a spherical balloon with a radius of 5.0 cm is 20.0 cm3. The balloon is then taken outside where its volume increases to 2.50 L. What is the outside temperature in °C, assuming no change in pressure?

To find the outside temperature of the balloon in degrees Celsius, we will use the ideal gas law and the relationship between temperature, volume, and pressure.
### Step 1: Understanding the problem
We're given that:
- Initial volume \( V_1 = 20.0 \, \text{cm}^3 \) (inside the balloon)
- Final volume \( V_2 = 2.50 \, \text{L} = 2500 \, \text{cm}^3 \) (outside the balloon)
- We assume constant pressure.
### Step 2: Using the formula relating volumes and temperatures
According to Charles' Law, if the pressure is constant, the ratio of the volumes of a gas to its corresponding temperatures (in Kelvin) is constant:
\[
\frac{V_1}{T_1} = \frac{V_2}{T_2}
\]
Where:
- \( V_1 \) is the initial volume (20.0 cm³),
- \( T_1 \) is the initial absolute temperature in Kelvin,
- \( V_2 \) is the final volume (2500 cm³),
- \( T_2 \) is the final absolute temperature in Kelvin.
### Step 3: Estimating the initial temperature
Since the problem doesn't provide the initial temperature, we can assume that the initial temperature \( T_1 \) was some standard room temperature (let's use room temperature as approximately 20°C, which is 293 K):
\[
T_1 = 20 + 273 = 293 \, \text{K}
\]
### Step 4: Rearranging the ideal gas law
Using the relationship from Charles’ law:
\[
T_2 = T_1 \cdot \frac{V_2}{V_1}
\]
### Step 5: Substituting the known values
Substituting the known values:
\[
T_2 = 293 \, \text{K} \cdot \frac{2500 \, \text{cm}^3}{20.0 \, \text{cm}^3}
\]
\[
T_2 = 293 \, \text{K} \cdot 125 = 36625 \, \text{K}
\]
### Step 6: Finding the final temperature in Celsius
This value seems unrealistically high; thus, it is indicative that either the initial estimate of the initial temperature is too low or simply the volume expands too much under certain conditions.
### Let's recalculate with the correct pressures or find absolute temperature changes only:
Assuming a more probable \( T_1\) change related to environments, it should be more local based on either outside conditions (assuming direct exposure):
Solving automatically for \( C\):
Example,
Using \( V1 = 20.0 \,cm^3\):
\[
T2 = 293 \cdot \frac{2500}{20} = 293 \cdot 125
= 36625 K = Backcheck in Celsius - 273
\]
In conclusion,
The relation thus mis-matched suggests directly within the confines of hills that our switch to Celsius:
