When does the deposition of solid particles occur?
only when the fluid transporting the sediments slows down or when glacial ice melts

conduction
Does crackling sound occur when PbNO3 is heated?
yes
How does convection of heat take place in liquids and gases?
The molecules get heated up ,gain energy and move to a new location thus transmitting heat from one part of the liquid to another.Similar things occur in gases. In the place being heated, the particles move more quickly because the heat energy is converted into kinetic energy in the particles. Faster moving particles collide more often and with more force and so they spread out, becoming less dense. Less dense fluids float on denser fluids so the heated particles start to rise. This has two effects. Firstly, denser, colder liquid cones in to replace the risen fluid, which can also be heated and rise. Also, the hotter, risen and more energetic particles start to transfer some of their energy to the colder fluid around them. This sets up a CONVECTION CURRENT of fluid rising where it is heated, spreading out at the top and falling back down in the colder parts of the fluid. and moving along the bottom to replace the rising warmed fluid. This carries the heat to the whole of the fluid.
How do particles behave when boiling?
There is a scientific explanation to why convection, and convection currents occur. Firstly, when the fluid is heated, the particles vibrate more and move further away from each other, decreasing the density of the fluid. This lighter fluid then rises above the denser fluid. While it is rising, the newly heated fluid cools, and this makes the particles oscillate less, making them closer together, and increasing the density of that part of the fluid, making it sink. This cycle is repeated to create a convection current
Why a solid metal expands when it is heated?
Metal expands when it is headed, Because of a process called melting , the more you heat a substance the more it will expand, ( the atoms ) will will get to a point where it will become a liquid and if heated enough the atoms will get so far apart that it will become a gas.
What processes occur when a fluid or semi solid is heated?
convection
Will a reaction occur when copper is heated with iron oxide?
J
What happens if water gets heated?
it will now occur evaporation
When does phase changes occur?
When a solid melts or changes to a liquid. When a liquid boils or changes to a gas. or the reverse when a gas condenses to a liquid or a liquid freezes to a solid. Also it is possible for a solid to go directly to a gas without passing through the liquid stage. This is called sublimation and can occur with sulfur when heated, or ice in the winter when the sun shines on it..
Why does evaporation occur rapidly at a higher temperature?
Because the faster particles move (particles move faster when heated -particle theory-) the faster they bounce off each other. Energy is used to break apart the bond that liquids have (fairly tight, sort of loose) and transform them into gas particles, which often leave a damp residue on a window, glass, etc.
