Temperature and Zeroth low of thermodynamic
🌡️ What is Temperature? Temperature is the measure of how hot or cold something is. 👉 Scientifically, it tells us how fast the particles (atoms or molecules) in a substance are moving. If particles move faster, the object is hotter → High temperature. If particles move slower, the object is colder → Low temperature. 🧠 Think of it like this: Temperature is like a speedometer for atoms — it tells how energetic they are. --- 🔁 Zeroth Law of Thermodynamics This law helps us define temperature clearly. ✅ Statement: “If object A is in thermal equilibrium with object B, and object B is in thermal equilibrium with object C, then object A is also in thermal equilibrium with object C.” 🧠 In Simple Words: If two things are the same temperature as a third thing, then they are the same temperature as each other. 🔥 Why is this law important? It helps us use thermometers. It tells us that temperature is a common measurable quantity. --- 📏 Scales of Temperature There are 3 main scales to m...
