Chihiro was boiling water to make pasta. As the water started boiling, bubbles formed on the surface and steam rose. What caused the appearance of the water to change?
The heat caused some of the water molecules to move apart from each other, becoming less dense and floating on the surface.
The heat caused some of the water molecules to move apart from each other, becoming less dense and rising from the pot.
The heat caused some of the water molecules to move closer together, becoming more dense and floating on the surface.
The heat caused some of the water molecules to move closer together, becoming more dense and rising from the pot.

gas to liquid
liquid to solid
The following graph shows the change in temperature of a 100-kilogram sample of a substance as it absorbs heat at a constant rate of 150 kilojoules per minute. For which intervals on the graph is the average kinetic energy of the molecules constant?
BC and DE
DE and EF
AB and BC
AB,CD, and EF
A glass of water is at room temperature in an isolated system. What will happen if one ice cube is added to the system?
Heat will be removed from the system, causing the liquid water to lose some molecular motion but retain its state.
Heat will be removed from the system, causing the liquid water to lose some molecular motion and change state.
Heat will be added to the system, causing the liquid water to gain some molecular motion but retain its state.
Heat will be added to the system, causing the liquid water to gain some molecular motion and change state.

A substance is heated at a constant
rate, and the temperature is recorded over time. A graph of the data is shown. Which statement best describes why the temperature remains constant during certain time intervals?
Heat is not distributed evenly throughout the substance
Energy is required to change the phase of the substance.
Electrons in the atoms are set free at certain temperatures.
Energy levels in the atoms absorb energy in specific amounts.
The diagram shows the changes that occur when an ice cube changes from solid state to steam. What does the constant temperature in Leg 4 indicate in terms of energy loss or gain?
Heat change cannot be predicted using given data.
Heat is gained to change the water to steam.
Heat is gained as the ice melts.
Heat is lost during this part of the reaction.
Density is a measure of
