Week 16 Matter

Mr. Balskey places an apple on a scale. The apple weighs 100 grams. He cuts the apple into four equal pieces and puts them all on the scale. What is the mass of the apple slices?

• 100 g

• 125 g

• 25 g

• 50 g

Which TWO of the following changes can be classified as physical? on a warm day.

• Ice melting

• Fireworks going off on July 4th

• A sandwich being digested.

• An egg cooking in a frying pan.

• Glass shattering as it hits the floor.

Mr. Balskey and Ms. Umphenour are conducting an experiment. They place six cubes into a beaker and find the combined mass. They allow the ice cubes to melt and find the combined mass of the beaker and the liquid water. What can students expect to be true about the two masses?

• The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.

• The mass of the ice cubes and the water will be equal because their particles have the same amount of energy.

• The mass of the ice cubes will be greater because solids are more dense.

• The mass of the ice cubes will be greater because they took up more space in the beaker.

Mr. Balskey wanted to determine the density of a colorful stone that he had picked up on the beach. Which two properties must Mr. Balskey measure in order to calculate the density of the stone?

• Mass and Temperature

• Composition and Texture

• Size and Shape

• Mass and Volume

Which statement summarizes the law of conservation of mass?

• During a chemical reaction, volume is not increased or decreased.

• During a chemical reaction, temperature is not increased or decreased.

• During a chemical reaction, energy is not created or destroyed.

• During a chemical reaction, mass is neither created or destroyed.

When you heat a sample of a gas, what happens to the particles that make up that gas?

• They become much smaller and take up less space.

• They become much larger and take up more space.

• They move faster and spread apart.

• They move slower and become more dense.

Copper and other metals are often used in making pots and pans to cook in. What property would best explain why?

• Solubility because it is a chemical property.

• Flammability because it is a physical property.

• Thermal conductivity because it is a physical property.

• Electrical conductivity because it is a chemical property.

Which of the following best describes the particle movement in a solid?

• The particles of a solid can move in random directions.

• the particles of a solid vibrate but do not move past one another.

• The particles are not attracted to each other.

• The particles of a solid can move past one another.

Glass starts out as a mixture of mostly solid sand particles. However, in order to mold or blow glass, the particles must change phase to the liquid state. How can the sand's state be changed?

• By decreasing the mass of the sand system to weaken bonds between solid particles and decrease freedom of motion.

• By adding a lot of heat to the sand system to weaken the bonds between solid particles and increase freedom of motion.

• By removing all the heat from the sand system to strengthen bonds between solid particles and decrease freedom of motion.

• By increasing the density of the sand system to strengthen bonds between solid particles and increase freedom of motion.
