Heat vs temperature - what's the difference? ๐
-
Temperature (T)
- A measure of how hot or cold something is.
- ๐ Think of it as: The "mood" of the particles. Are they chill (low energy) or hyper (high energy)?
- Example: You judge if your coffee is warm enough by checking its temperature.
-
Heat (q)
- The energy transferred between bodies because of a temperature difference.
- ๐ฅ Fact: It can make things do stuff! Like boiling water or melting ice.
- Example: On a sunny day, you feel warm because heat (or thermal energy) from the sun transfers to you.
State functions - it's all about the destination, not the journey! ๐
- Key Point: State functions only care about the start and the end. The journey in between? Meh! They don't care.
- Examples of State Functions
- Temperature (T)
- Volume
- Enthalpy
- Pressure
- Real-world Analogy
- Imagine checking your bank balance at the beginning and end of the month. It doesn't show each purchase (the path) but just the initial and final amounts.
The nitty-gritty of heat ๐ฅ
- How is Heat Transferred?
- Conduction: Touch! Like a metal spoon heating up in a hot soup.
- Convection: Movement! Warm air rises, cool air sinks.
- Radiation: Invisible waves! How the sun warms the Earth.
- Effects of Heat:
- Increases the average kinetic energy of particles.
- Can lead to phase changes, like turning water to steam.
