To condense a subject you must reduce temperature. Reducing the temperature of a substance reduces the amount of heat that the object has, which means less thermal energy. Thermal energy is the energy of molecular motion, so when you reduce it, molecular motion slows.
When a solid changes to a liquid, the particles gain energy and start moving faster, causing the solid to melt into a liquid. So, in this process, the particles speed up.
they move faster, eventually changing the solid into a liquid
When water changes from a solid to a liquid, it undergoes melting. When it changes from a liquid to a vapor, it undergoes evaporation. These changes are driven by increases in temperature and energy levels.
seismic wave travels faster through solid rock and slower through water, but i dont know why!
Radiation moves at the speed of light in a vacuum (approximately 299,792 kilometers per second). In a solid or liquid medium, the speed of radiation is slightly slower due to interactions with the medium's atoms or molecules. In a gas, radiation can travel faster compared to a solid or liquid but still slower than in a vacuum due to lower interaction with gas particles.
Faster.
Assuming you mean changes of state i.e. solid to liquid, then if energy is supplied to matter then the particles or atoms move faster as they gain kinetic energy. This causes the bonds between the atoms to break, allowing the particles to flow over each other, as in a liquid. Like matter, energy is never created or destroyed in chemical reactions. Or: Every chemical change in matter includes a change in energy.
I might be wrong, but I would say slower. If you mean energy in form of heat, molecules move slower if the liquid is colder, so if a liquid releases energy in form of heat (turns ¨cooler¨), than the molecules move slower. As I said, I might be wrong. Just my thoughts
Energy is used when water changes from a solid to a liquid.
During thermal conduction in a solid, kinetic energy is transferred from faster-moving particles to slower-moving particles. This leads to an overall increase in the speed of slower particles and a decrease in the speed of faster particles, resulting in a more uniform distribution of particle speeds.
When a solid changes to a liquid, the particles gain energy and start moving faster, causing the solid to melt into a liquid. So, in this process, the particles speed up.
energy is gained!
No. Gas particles move much faster than solid particles.
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
Mechanical waves (like seismic waves) will travel faster through a solid than a liquid.
gliding movement. The particles move faster then that of a solid, but slower than that of a gas.
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
