When a metal bar is heated....the particles in the area of the metal bar that is hot start vibrating.. knocking into each other and passing the heat energy on to cooler particles. The cooler end that isn't heated still has a rise in temperature just not as much as the heated area because the heat has almost been diluted.
The density will decrease because the heated metal contracts and its particles slow down.
The term is thermal expansion. When metal is heated, its particles gain kinetic energy and vibrate more vigorously, causing the metal to expand due to the increased space between the particles.
When a metal is heated to a high temperature, its particles vibrate more rapidly, increasing kinetic energy and causing thermal expansion. This can lead to changes in the metal's properties, such as increased ductility or changes in its crystal structure. At even higher temperatures, the metal can eventually melt and become a liquid.
When a liquid is heated, the particles gain kinetic energy and move faster, causing the interparticle spaces to increase. This expansion leads to a decrease in the liquid's density as the particles spread out more.
When particles are heated, they gain energy, which leads to an increase in their kinetic energy. As a result, the speed at which the particles move increases. This heightened movement can cause substances to expand and can affect their state, such as transitioning from solid to liquid or from liquid to gas. The overall effect is a more rapid and energetic motion of the particles.
The density will decrease because the heated metal contracts and its particles slow down.
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
The term is thermal expansion. When metal is heated, its particles gain kinetic energy and vibrate more vigorously, causing the metal to expand due to the increased space between the particles.
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
they get excited and move around faster
When a metal is heated to a high temperature, its particles vibrate more rapidly, increasing kinetic energy and causing thermal expansion. This can lead to changes in the metal's properties, such as increased ductility or changes in its crystal structure. At even higher temperatures, the metal can eventually melt and become a liquid.
its resistence considerably decreases
it wil expand
The particles start moving faster and the matter expands.
When one end of a metal is heated, the particles at that end begin to vibrate more rapidly, transferring kinetic energy to neighboring particles along the metal. This causes the metal to conduct heat from the hot end to the cooler end, resulting in the temperature of the entire metal eventually equalizing.
The atoms that make up the metal are loosened up by the heat, therefore causing the metal structure to become more flexible.
When a substance is heated, the kinetic energy of its particles increases. This leads to the particles moving faster and colliding more frequently with each other and the container they are in.
