* (3) What is meant by latent heat? How will thestate of matter transform if latent heat is givenoff? |
| Answer» <p>Normally when heat energy is added to or removed from an object, the temperature of the object changes; however, during state changes, the temperature of an object stays constant. The temperature remains the same because energy is required for an object to change phases.</p><p>Latent heatis the heat energy per mass unit required for a phase change to occur. If we think about substances at a molecular level, gaseous molecules have more vibration than liquid molecules. So when you add heat to a liquid, you are actually causing the molecules to vibrate. The latent heat is the energy required to change the molecular movement. Each substance has a unique latent heat value.</p><p>state of matter transforms from gas to liquid and from liquid to solid if the latent heat is given off.</p> | |
