Latent Heat and Kelvin: Challenge Paper
An Olympiad-style paper: 10 questions in 20 minutes, +3 for a right answer and -1 for a wrong one. Melting and warming in one go, ice to cool a drink, the heating curve, steam burns, dry ice and separating by sublimation. Every answer has a worked solution that names the usual slip.

Before you start
- It runs like an online exam: one question at a time, with a palette showing what you have answered, skipped or marked for review.
- The clock starts when you press Begin the test, after you have read the instructions, and keeps running even if you reload or leave. At zero, your saved answers are submitted.
- Leaving the test window is recorded, and your teacher can see it.
- Your score, the answers and the explanations show when you finish, with where you stand among everyone who has taken it.
