What happens to the temperature of ice as it continues to absorb energy during melting?
What happens to the temperature of ice as it continues to absorb energy during melting?
- It decreases until it reaches the freezing point.
- It rapidly increases until it starts boiling.
- It remains constant as the ice melts. (correct)
- It fluctuates between freezing and melting points.
Why does crushed ice melt faster than cubed ice?
Why does crushed ice melt faster than cubed ice?
- Crushed ice absorbs more heat due to its smaller mass.
- Crushed ice is made of smaller water molecules.
- Crushed ice retains heat longer than cubed ice.
- Crushed ice has a larger surface area for energy absorption. (correct)
What best describes the temperature of water when it reaches the boiling point?
What best describes the temperature of water when it reaches the boiling point?
- It decreases gradually as steam forms.
- It continues to increase until all water is evaporated.
- It fluctuates back and forth between boiling and freezing points.
- It remains constant as energy is absorbed for boiling. (correct)

Flashcards
Melting Point of Ice
Melting Point of Ice
The temperature at which ice changes state from solid to liquid. The temperature remains constant during melting.
Boiling Point of Water
Boiling Point of Water
The temperature at which water changes state from liquid to gas (steam). The temperature remains constant during boiling.
Heat Absorption during Phase Changes
Heat Absorption during Phase Changes
Ice and water absorb energy from the surroundings during melting and boiling, respectively. This energy is used to break the bonds between molecules.

Study Notes
Temperature Changes During Phase Transitions
- A graph of temperature against time for ice or water shows specific patterns
- The temperature of ice initially rises
- During melting, the temperature remains constant while ice changes to water
- The temperature of water then rises
- During boiling, the temperature remains constant while water changes to steam
- Crushed ice melts faster than cubed ice because of increased surface area for absorbing energy from the surroundings.
