What effects does heat have on matter?

Answer 1

When heat is added to something it causes the atoms to interact together faster, such as vibrating faster. This causes the space between the atoms to increase which in turn casues the substance to expand and takes up more space.

Here's the opposite: When it gets cold, there's less space and therefore eventually it becomes a solid.

So with that in mind you have ice. Add heat, the atoms begging to vibrate faster causing the spaces to get bigger which causes the ice to melt.

Answer 2

It heats up the material by making each atom and/or molecule move faster.

If the heat is great enough the if might melt it (or vaporize) it,

it might cause (or speed up) chemical changes such as decomposition.

Answer 3

yes, as particles get hotter they gain energy allowing them to move away. for example, the particles in a solid are closer together than the particles in a liquid so as they gain energy they can space out making them change states.

Answer 4

Heat does multiple things to matter. One example is that it increases the vicosity in liquids. Vicosity is how easily liquids flow. Another example is that when enough heat is applied, it will melt solids. Some solids melt at low temperatures, like ice, and some melt at very high temperatures like gold. The lack of heat freezes solids at certain points.

Answer 5

Heat causes the particles of an object to speed up in movement. This raises the obect's average kinetic energy, or temperature. When an object touches or is near something else which has a lower temperature, it looses its heat to that object because its particles are slowing down. That is why hot air rises, because it is less dense because the particles are spread out from rapid movement, whereas cold air sinks because its particles are more dense because of the slower movement.

Answer 6

heat speeds up the molecules in the substance in all states of matter. for solids, when movement of molecules becomes so fast and molecules start moving freely, leaving their fixed postion otherwise, we say the solid is melted and changed into liquid. Subsiquenlty when liquid is heated furthur it changes inti gas

Answer 7

based on our previous lessons there are 3 effects of heat in matter:

1.it changes size

2.it changes temperature

3.it changes state

Answer 8

it changes size, it changes temperature and it changes state

Answer 9

Heat causes the molecules in a form of matter to accelerate (reason why ice becomes water, and water becomes gaseous water vapor).
