🌡️ Temperature vs Heat
Learn to distinguish between temperature and heat—two related but different concepts in physics. Temperature measures the average kinetic energy of particles, while heat is the transfer of thermal energy from one object to another. This quiz explores temperature scales (Celsius and Kelvin), conversions between them, and why understanding the difference matters in real-world applications. **What you'll learn:** - The difference between temperature and heat - How temperature is measured and expressed in different scales - How to convert between Celsius and Kelvin scales - Why materials with the same temperature can transfer different amounts of heat
