Can anyone help me with a physical science study guide?
3. Thermal expansion is the expansion in volume of an object based on how much energy is added to it. When more energy is added, particles accelerate, relating the Kinetic Theory to thermal expansion. 4. Exothermic – the release of heat Endothermic – the absorption of heat They are both processes of heat transfer which work together to explain the differences felt in heat. 5. evaportation – (liquid to gas) endothermic condensation – (gas to liquid) exothermic freezing – (liquid to solid) exothermic boiling – (liquid to gas) endothermic Changes of physical state are caused by either endothermic or exothermic reactions. 6. As more thermal energy is added to an object, the object’s particles have higher pressure and velocity, which relates to the kinetic theory. 7. ice cube – little kinetic energy (solid) lukewarm bath – medium kinetic energy (liquid) textbook – little kinetic energy (solid) hot coffee – high kinetic energy (liquid and gas vapor) 8. ice cube – little thermal energy (cold)
