2) A balloon was inflated to a volume of 5.0 liters at a temperature of 7.0°C. It landed in an oven and was heated to 147°C. What is its new
volume?

6.12 L

Explanation:

Given that,

Initial volume, V₁ = 5 L

Initial temperature, T₁ = 7.0°C = 343 K

Final temperature, T₂ = 147°C = 420 K

We need to find its new volume. The relation between volume and temperature is given by :

So, the new volume is 6.12 L.
