The mass of the liquid
decreases.
The temperature of the liquid
decreases.
The molecules of the liquid

A student makes this particle model of atoms that make up part of the bridge. The model shows the atoms when the bridge is at 18°C.
The student wants to make a new model to show the atoms when the bridge is heated to 23°C.
Which of the following changes should the student include in the new model?
making the atoms bigger
making the atoms a different shape
making larger spaces between the atoms
making chemical bonds between the atoms
Small earthquakes are relatively common near the Golden Gate Bridge, but major earthquakes occur less often. Major earthquakes only occur when a large amount of energy is carried by seismic waves.
Which of the following must be large for a major earthquake to occur?
the speed of the seismic waves
the frequency of the seismic waves
the amplitude of the seismic waves
the wavelength of the seismic waves
The diagrams represent the movement of particles in two samples of the same gas. The samples are in identical, closed, glass containers. The length of an arrow represents the speed of a gas particle.
Which of the following must be different between the two samples?
color
mass
temperature
volume
A student measured three objects made of different materials. The table shows each object’s mass and volume.
Order the materials from least dense to most dense, write the number in the correct order.
1. glass 2. rubber 3. wood
(a)
Four objects have different forces applied to them. All of the horizontal forces acting on each object are shown in the diagrams.
Check each diagram to show whether the speed of the object is changing.
Several objects are located on a set of shelves in a classroom. The mass of each object is given in the table.
bowl
school supply box
rubber ball
lunch box
Which of the following is the best example of heat being transferred by conduction?
ocean currents moving warm water to cold water
mountain boulders warming up in bright sunlight
rocks buried in sand absorbing heat from surrounding sand
air masses moving from high-pressure to low-pressure regions
