Question
**Educational Text Transcription:** ### Thermodynamic Calculations: Heat Release in Freezing Water #### Introduction Understanding the energy changes involved in phase transitions is crucial in thermodynamics. When water freezes, energy is released in the form of heat. This process can be quantified using kilocalories per mole. **Given Data:** - Converting liquid water to solid ice releases \( 1.4 \, \text{kcal/mol} \). #### Problem Statement **Part C:** - **Question**: How many kilocalories are released by freezing \( 4.3 \, \text{mol} \) of \( \text{H}_2\text{O} \)? - **Instruction**: Express your answer using two significant figures. **Part D:** - **Question**: How many kilocalories are released by freezing \( 23 \, \text{g} \) of \( \text{H}_2\text{O} \)? - **Instruction**: Express your answer using two significant figures. #### Answer Boxes: - **For both parts**, there are text input fields where students can enter their answers in kilocalories, along with a 'Submit' button and a 'Request Answer' link for additional assistance. By solving these problems, students will enhance their understanding of energy changes during phase transitions and practice using significant figures in calculations.
