Question

An experiment was carried out by a grade 9 student to investigate how long it will take to convert ice to water vapour by increasing its kinetic energy. She plotted her results on the graph below. Study the graph and answer the following questions. the heating curve Q1. What is the state at sections A and C? A________________________________________ C________________________________________ Q2. Sections B and D have a mixture of two states, list them B_________________________________________ D_________________________________________ Q3. How does she increase the kinetic energy of the particles of the ice? _______________________________________________________________________ Q4. State the use of the energy supplied in each of the sections A: _________________________________________________________________________ B: _________________________________________________________________________ C: _________________________________________________________________________ D: _________________________________________________________________________ Q5.
