All solids are hard and brittle.

What has a definite volume and shape.

Nico is sorting foods into categories. He is not certain about jelly. He notices on a spoon it has a definite shape and volume until you tip the spoon. Does this liquid have low or high viscosity.

Would you feel like a superhero if you could melt metal just by holding it? The element gallium is a solid at room temperature, but it will reach its melting point and melt if you hold it in your hand. If you pour the liquid gallium into a container at room temperature, it will become solid again. How do the melting point and the freezing point of gallium compare to each other?

Temperature does not affect pressure of a ball.

You can increase thermal energy by heating it.

What has no definite volume or shape.

Gloria's family built a new deck using building materials made from recycled plastic bottles. As they were heated, the plastics softened and were formed into new shapes. These plastics were (amorphous / crystalline) solids, and their particles are arranged (in no regular pattern / in regular, repeating patterns).

Min was writing about changes in the state of matter for a research paper. Which of these changes might she include as examples of sublimation? A. Dry ice changes directly to carbon dioxide gas or B. An ice cube melts on the floor, then evaporates.

Honey does not have very high viscosity.

Crystalline solids do not form a pattern.

What has no definite volume or shape.

A scout on a hike becomes lost. He does not have a compass, but he does have a small needle, a magnet, and some water. He magnetizes the needle and then gently places it on the surface of the water, where it points to the north. What property of the water makes it possible for the needle to lie on the surface of the water? A. Viscosity B. definite volume C. surface tension or D. Boiling Point

Ruth’s birthday celebration included several party balloons that were filled with helium. As afternoon sunlight filled the room over time, the room became warmer. As the temperature in the room increased, the volume of the gas in the balloons (decreased / increased / stayed the same), because gas temperature and volume are (directly proportional / indirectly proportional ).

The particles that make up a solid are closely packed.

Dry ice is an example of sublimation.

What is energy that is in motion.

People who have certain lung diseases, such as emphysema or lung cancer, often have to use oxygen from tanks. A large volume of oxygen can be put into a small tank because oxygen is a gas, and gases can be_______________.

The pistons in an engine show how gas behavior can be applied to everyday events. Volume, temperature, and pressure of a gas are all involved in the working of pistons. According to BOYLES'S LAW what happens?

Crystalline solids melt at a certain melting point

Sublimation occurs when the surface particles of a solid melt to a liquid, and then a gas.

What is the total kinetic and potential energy of all the particles in an object or substance.

Nakeem and his team were playing basketball in the gym, and all the basketballs were firm and bounced well. When the team went outside, the same basketballs seemed a bit flat and would not bounce well. What happened?

Chase and Bernie were ice-fishing at a frozen pond where the temperature was –4⁰C. As the boys sat on the ice, the thermal energy of the ice (decreased / increased ), and some of the ice (condensed / melted). As it sat in the cold air, the thermal energy of the water on the glove (decreased / increased), and the water on the glove (froze / melted).

If a ball is left outside in a cooler temperature then the volume will increase causing it to change the physical properties of the ball.
