Liquid is a state of matter with a definite volume but no definite shape, and water is a common example of a liquid that can flow and take the shape of its container.
29. What state of matter has the least energy?
Solids have the least energy as their particles are held closely together in a fixed arrangement.
30. Which of the following is an example of a gas?
Oxygen is a gas essential for respiration, while steel, iron, and gold are examples of solid metals.
31. What happens to particles in matter when it changes state?
When matter changes state (e.g., from solid to liquid), the particles rearrange themselves rather than disappear or stop moving.
32. Which state of matter has a definite shape but no definite volume?
Solids have a definite shape due to the arrangement of their particles but no definite volume because they can be compressed.
33. What state of matter has the most disorganized particles?
Gases have the most disorganized particles because they are far apart and move freely in all directions.
34. Which of the following is an example of a solid?
Solids have a definite shape and volume, and ice, which is frozen water, maintains its shape and volume.
35. What state of matter has the highest kinetic energy?
Plasma has the highest kinetic energy because its particles move at high speeds due to their high temperature.
36. Which of the following is an example of a plasma?
Plasma is a state of matter with highly energetic ions and electrons that can conduct electricity, such as in neon lights.
37. What state of matter has the most tightly packed particles?
Solids have the most tightly packed particles compared to liquids, gases, and plasmas, leading to their fixed shape and volume.
38. Which of the following is an example of a gas?
Oxygen is a gas essential for respiration, while steel, iron, and gold are examples of solid metals.
39. What is the process of a liquid changing into a gas called?
Evaporation is the process by which a liquid changes into a gas, usually due to an increase in temperature.
40. What happens to the volume of a gas when its temperature increases?
When the temperature of a gas increases, its particles gain more kinetic energy, leading to increased movement and greater volume.
41. What is the ability of a substance to be hammered into thin sheets called?
Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets without breaking.
42. Which of the following is an example of a chemical change in matter?
Rusting iron is a chemical change as the iron particles react with oxygen and moisture in the air to produce iron oxide (rust), altering its chemical composition.
43. What is the amount of matter in an object called?
Mass is the measure of the amount of matter in an object and is typically measured in units like kilograms or grams.
44. What is the process of a gas changing into a liquid called?
Condensation is the process by which a gas changes into a liquid, usually due to a decrease in temperature or increase in pressure.
45. Which of the following is an example of a physical property of matter?
Density is a physical property of matter that describes the mass of a substance per unit volume and can be measured without changing the substance's composition.
46. What is the ability of a substance to be drawn into a wire called?
Ductility is the property of a substance that allows it to be drawn into thin wires without breaking, making it useful for electrical wiring.
47. Which of the following is an example of a physical change in matter?
Boiling water is a physical change as it transitions from a liquid to a gas without changing its chemical composition.
48. What is the measure of the gravitational force acting on an object called?
Weight is the measure of the gravitational force acting on an object's mass and is dependent on the acceleration due to gravity.
49. What state of matter has an indefinite shape and volume?
Gases have an indefinite shape and volume as their particles are free to move and compressible, adapting to the container they are in.
50. Which of the following is an example of a gas?
Oxygen is a gas essential for respiration, while steel, iron, and gold are examples of solid metals.
51. What is the property of matter to resist a change in motion called?
Inertia is the property of matter that causes an object to resist changes in its state of motion, either staying at rest or moving with constant velocity.
52. What is the process of a solid changing into a liquid called?
Melting is the process by which a solid changes into a liquid, typically due to an increase in temperature beyond its melting point.
53. What is the property of matter to conduct electricity called?
Conductivity is the property of matter that allows it to conduct electricity or heat, such as in metals or other conductive materials.
54. Which of the following is an example of a chemical property of matter?
Flammability is a chemical property that describes a substance's ability to burn or support combustion, indicating its reactivity with oxygen.
55. What is the process of a liquid changing into a solid called?
Freezing is the process by which a liquid changes into a solid, usually due to a decrease in temperature below its freezing point.
56. Which of the following is an example of a liquid?
Liquid is a state of matter with a definite volume but no definite shape, and water is a common example of a liquid that can flow and take the shape of its container.
57. What is the density of an object with a mass of 50g and a volume of 10cm3?
Density is calculated by dividing the mass of an object by its volume; in this case, 50g รท 10cm3 = 5 g/cm3.
58. What is the measure of the amount of space an object occupies called?
Volume is the measure of the amount of space occupied by an object in three dimensions and is commonly measured in units like cubic centimeters (cm3).
59. What is the process of a liquid changing into a gas called without boiling?
Evaporation is the process by which a liquid changes into a gas at the surface without reaching its boiling point, such as water drying on a towel.
60. What state of matter has an indefinite shape but a definite volume?
Liquids have an indefinite shape but a definite volume, allowing them to flow and take the shape of their container while maintaining a set volume.
61. Which of the following is an example of a chemical change in matter?
Rusting iron is a chemical change as the iron particles react with oxygen and moisture in the air to produce iron oxide (rust), altering its chemical composition.
