Question
### Problem Statement A cell is roughly spherical with a radius of \(2.78 \times 10^{-5} \, \text{m}\). **Task:** Calculate the work required to expand the cell surface against the surface tension of the surroundings if the radius increases by a factor of three. Assume the cell is surrounded by pure water and that \( T = 298.15 \, \text{K} \). Express your answer with the appropriate units. ### Interactive Area - Input Field: Users can enter their answer in scientific notation. - Tools: Buttons are available for different mathematical expressions and units. ### Answer Submission - **Attempted Answer:** \( W_{\text{rev}} = 5.59 \times 10^{-6} \, \text{J} \) - Status: Incorrect; Try Again - Attempts Remaining: 3 ### Additional Features - Links are provided for "Review," "Constants," and "Periodic Table" for further reference. - Buttons for previous answers and request for the correct answer are available. This interface is designed to help students apply theoretical knowledge to practical problems in physics, specifically focusing on work, energy, and surface tension in a thermodynamic context.
