Challenge Problems
Push your limits with challenges.
Question 1
A helium balloon is released at sea level. If it rises to 3000 meters where the temperature drops by 10 degrees Celsius, calculate the pressure change in the balloon if initially, it was 101.3 kPa.
💡 Hint: Remember how temperature and pressure are interconnected in gas laws.
Question 2
Calculate the surface tension force in a droplet with a radius of 0.2 mm. Given that the surface tension of water at room temperature is 0.072 N/m, find the pressure difference across the droplet's surface.
💡 Hint: Focus on the relationship between surface tension and pressure difference in a droplet.
