Passage
Heat transfer is the movement of thermal energy (or heat) from one body to another.
Conduction is the flow of thermal energy from a higher temperature to a lower temperature
through direct contact. Convection is the transfer of thermal energy in a liquid or gas by the
physical circulation of currents from one region to another. Radiation is the transfer of heat by
electromagnetic waves through space.
Experiment 1
A 50 g metal rod at 23 °C was placed in a water bath held at a constant 100 °C. The student
measured the temperature of the rod as it was heated by convection in the water. Table 1 shows

Passage I
Hooke's Law says that the force that a spring exerts is equal to the negative of its spring
constant times the distance that the spring is stretched or compressed.
The spring constant is fixed for any specific spring. Also, when a spring is stretched or
compressed, it stores elastic potential energy equal to one-half the spring constant times the
stretched or compressed distance squared:
Experiment 1
A student used a spring scale to measure the force required to compress two different springs.
The resulting data can be found in Figure 1.
Experiment 2
A 200 g mass was placed on top of Spring A from Experiment 1. The spring was compressed
a specified distance and then released, launching the mass into the air. The mass’s maximum
height was measured. The experiment was repeated for different compression distances. The
same experiment was repeated for a 100 g mass. The resulting data can be found in Figure 2.
4. If both the 100 g mass and the 200 g mass were launched to a height of 10 cm, which of the
following is true?
A. The spring was compressed 2 cm farther for the 200 g mass than for the 100 g mass.
B. The spring was compressed 1 cm farther for the 100 g mass than for the 200 g mass.
C. The spring was compressed twice as far for the 200 g mass than for the 100 g mass.
D. The spring was compressed 1 cm farther for the 200 g mass than for the 100 g mass.
5. According to Figure 2, what was the difference in the launch heights for the 100 g and 200 g
masses when the spring was compressed 4 cm?
A. 18 cm
B. 36 cm
C. 10 cm
D. 54 cm

Passage I
Hooke's Law says that the force that a spring exerts is equal to the negative of its spring
constant times the distance that the spring is stretched or compressed.
The spring constant is fixed for any specific spring. Also, when a spring is stretched or
compressed, it stores elastic potential energy equal to one-half the spring constant times the
stretched or compressed distance squared:
Experiment 1
A student used a spring scale to measure the force required to compress two different springs.
The resulting data can be found in Figure 1.
Experiment 2
A 200 g mass was placed on top of Spring A from Experiment 1. The spring was compressed
a specified distance and then released, launching the mass into the air. The mass’s maximum
height was measured. The experiment was repeated for different compression distances. The
same experiment was repeated for a 100 g mass. The resulting data can be found in Figure 2.
25. When Spring A was compressed 3 cm, compared to the height reached by the 200 g mass,
the height reached by the 100 g mass was:
A. half as high.
B. three times as high.
C. twice as high.
D. the same height.

Passage
Heat transfer is the movement of thermal energy (or heat) from one body to another.
Conduction is the flow of thermal energy from a higher temperature to a lower temperature
through direct contact. Convection is the transfer of thermal energy in a liquid or gas by the
physical circulation of currents from one region to another. Radiation is the transfer of heat by
electromagnetic waves through space.
Experiment 1
