41. What is the process of changing from a solid state directly to a gas state called?
Sublimation is the process of changing from a solid state directly to a gas state without passing through the liquid state.
42. Which of the following can change from a liquid to a gas state at room temperature?
Water can change from a liquid to a gas state at room temperature through the process of evaporation.
43. What happens to a substance during the process of freezing?
During freezing, a substance changes from a liquid state to a solid state as it loses heat energy.
44. Which of the following processes involves the conversion of a gas to a liquid?
Condensation is the process of changing a gas to a liquid as it loses heat energy and condenses.
45. What is the process called when a liquid is heated and turns into a gas?
Evaporation is the process of turning a liquid into a gas when heated, usually to its boiling point.
46. What happens to the particles of a substance during the process of melting?
During melting, the particles of a substance gain energy, overcome attraction forces, and move more freely, resulting in a change from a solid to a liquid state.
47. At what temperature does water boil and change from a liquid to a gas?
Water boils at 100°C, and at this temperature, it changes from a liquid state to a gaseous state.
48. In which state of matter do the particles have the least energy and are closest together?
In a solid state, the particles have the least energy and are closely packed together in an organized structure.
49. Which of the following processes involves a change from a gas directly to a solid without passing through the liquid state?
Sublimation is the process of changing from a gas directly to a solid without transitioning through the liquid state.
50. What is the opposite process of sublimation?
Deposition is the opposite of sublimation and involves the direct change of a gas to a solid without becoming a liquid.
