6.4 ; internal energy
Fichas del conjunto (7)
- 1define thermal energythe total energy of an object due to the kinetic energy of its atoms and/or molecules depending on its mass
- 2define temperaturea measure of the average kinetic energy of molecules
- 3What does internal energy consist of?1. the kinetic energy of atoms
2. the potential energy due to the intermolecular forces - 4What is internal energy?the total energy in the kinetic and potential energy stores of all the particles in the substance
- 5increasing the temperature == increases the internal energy
- 6The strength of the forces of attraction between the particles of a substance explain why it is a solid, liquid, or gas. Give examples• solid; strong forces of attraction
• liquid; weaker forces of attraction
• gas; insignificant forces of attraction - 7When a substance is heated:• if its temperature rises, the kinetic energy of its particles increase
• if it melts or boils, the potential energy of its particles increase
