Study Notes
Heat and Temperature
- Heat is the total energy of all particles in an object.
- Temperature is the average energy of particles in an object.
Heat Flow
- Heat (thermal energy) flows from areas or objects of high temperature to low temperature.
- The flow continues until the temperature becomes equal.
- When thermal equilibrium is achieved, the temperature is the same.
Rate of Heat Flow
- Rate of heat flow refers to how fast heat transfer occurs.
- The greater the difference in temperature between the hot and cold areas/objects, the faster heat will flow.
- For example, hot coffee in a cold room will cool down much faster than in a hot room.
Feeling Hot and Cold
- When we touch a hot object, heat flows into our hands.
- When we touch a cold object, heat flows out from our hands.
- We have special cells in our skin that detect heat transfer to and from our body.
Heat Dissipation
- Heat dissipation occurs when an object is hotter than the surrounding room temperature.
- Heat gradually dissipates from the object to the surroundings.
- Dissipation continues until the object reaches room temperature, achieving thermal equilibrium.
