Energy transfer and temperature quick check
1. How does energy transfer occur between objects at different temperatures?
- Energy transfer occurs through conduction, convection, or radiation. Heat flows from the object with higher temperature to the object with lower temperature until thermal equilibrium is reached.
2. What is the relationship between temperature and the average kinetic energy of particles in a substance?
- The temperature of a substance is directly proportional to the average kinetic energy of its particles. As the temperature increases, the average kinetic energy of the particles also increases.
3. How does thermal energy transfer affect the temperature of an object?
- Thermal energy transfer can either increase or decrease the temperature of an object, depending on whether heat is being added or removed from the object. Heat transfer from a warmer object to a cooler object will increase the temperature of the cooler object, while heat transfer from a cooler object to a warmer object will decrease the temperature of the warmer object.
