The 2025 Reference Tables hold data and equations you are expected to find and apply, not memorize. Every student gets a clean copy in the exam, so practice with them from the start.
Edition
2025, for Physical Science: Chemistry
In the exam
One clean copy for every student
Purpose
Locate and apply, not memorize
Calculator
Scientific; graphing allowed with memory cleared
Practice the way you will use them
Keep a copy beside you for every practice set, and find each value rather than recalling it.
Write the equation you choose before you put numbers in, with units on every value.
Check which table a question points to: the same quantity can appear for different conditions.

Questions in this course use the 2025 tables' values and equations exactly, and the worked answers say which value they used.

2
A student heats a gas in a cylinder with a freely moving piston, keeping the pressure constant, and records the volume at four kelvin temperatures. Which prediction for 500 K is supported by the data, and why?
Question 2
Specific heat capacities of four metals
Metal
Specific heat capacity (J/(g·°C))
aluminum
0.897
iron
0.449
copper
0.385
lead
0.129
To identify a metal, a student heats a 60.0 gram sample to 99.0 °C in boiling water and drops it into 120.0 grams of water at 21.0 °C in an insulated foam cup. The metal and the water both end at 24.4 °C. Assume all the heat lost by the metal is gained by the water. The specific heat capacity of water is 4.18 J/(g·°C). Using the table, which metal is the sample most likely to be?
