MATTER

QuestionAnswer
What shape are solids in?s Solids have a fixed shape as the particles are in a fixed pattern and do not move.
What volume are solids in? Solids have a fixed volume and cannot be compressed as the particles are close together
Do solids flow? Solids do not flow as strong forces hold the particles together.
What shape are liquids in? Liquids do not have a fixed shape as the particles can move and slide past each other they will take the shape of whatever container they are in.
What volume are liquids in? Liquids have a fixed volume and are very difficult to compress as the particles are close together.
Do liquids flow? Liquids do flow as the forces holding particles together are weaker than in solids,the particles slide past each other.
What shape are gasses in? Gasses do not have a fixed shape as the particles move continuously and randomly in all directions,they will take shape of whatever container they are in.
What volume are gasses in? Gasses do not have a fixed volume as the particles spread out in all directions,filling any available space.
Can gasses be compressed? Gasses can be compressed because the particles in a gas are far apart,sothey can be squeezed back together into a smaller volume.
Do gasses flow? Gasses do flow as the forces holding the particles are weak,the particles can move in all directions.
What is melting? Melting is the change of state from a solid to a liquid.
Explain melting works/process. When solids are heated,particles get energy and vibrate faster,more heat is supplied the more the particles vibrate,eventually forces holding particles together break and seperate moving and sliding past each other,solid is melting.
What is the melting point? Melting point of a solid is the temperature at which the solid becomes a liquid,melting point of ice is 0 Celsius.
What is evaporation? When a liquid changed to a gas at the surface of a liquid.
Explain evaporation works/process. When liquids are heated particles gain energy and move faster,evaporation occurs when particles on surface of lowuid build up enough energy to break free as gas,it can occur at any temp,even room temperature.
What is boiling? Boiling is when a liquid changes to a gas.
Explain how bling works When boiling point is reached,particles of gas form throughout the liquid,the new gas formed creates bubbles that escape from rhe liquid,when bubbles have formed throughout the liquid,its boiling,
What is the boiling point? The set temperature at which boiling occurs in a lowuid,diff liquids have diff boiling points,e.g for water it’s 100 celsuis
What is condensation Condensation is the change of state from a gas to a liquid
Explain how condensation works As the gas cools,heat is released and the particles lose energy,the particles losing energy caused it to move less and become closer together so the change of state in matter since particles are close together will condense to liquid.
What is freezing? Freezing is when lowuid changes to a solid
Explain how freezing works As the liquid cools,heat is released causing rhe particles to lose energy,stop moving become more packed together in a fixed pattern meaning its close enough together to form a solid shape,freezing into a solid
What is sublimination? When matter changes directly from a solid to a gas
Explain how sublimination works There’s not really a process for sublimination,like some solids change directly from a solid to gas and do not go through the middle stage of turning into liquid then solid,not everything can do this,only certain solids for example dry ice.
What is diffusion? Diffusion is the movement of particles from a area of high concentration to a n area of low concentration
What is the law of conservation mass? The law of conservation mass suggests matter cannot be created nor destroyed

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
