When a solid is heated the particles gain energy and start to vibrate faster and faster the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid The particles in the liquid are the same as in the solid but they have more energy
(particles after melting after melting?)
during melting, the particles start to move about staying close to their neighbouring particles then move more freely
Particles would move more freely, while still staying close together depending on the shape of the liquid
Explanation:
Melting is the process of going from a solid to a liquid due to the increase in heat/energy. This increase in heat/energy increases the speed at which the atoms within the object moves. Lets say we had an ice cube. While it is a cube, the particles inside the cube are slow and compact, staying close together.
When enough energy is gained, this makes the particles begin to move faster, gaining heat and energy which results in the ice cube melting and moving more freely than normal.
its not that hard, i mean its a question that you kinda have to answer yourself. its basically asking you to write down the items that your family brought over the last week. just think of the things that your parents or family brought home. then you have to tell them what packaging was around the items, for example, plastic. and then etc.
Since the speed in which the gas molecules are faster as they are heated, they fly around in the container and logically, it is harder to insert a moving object into water than something more stationary or slower.
