Charles’s and Boyle’s Laws is a free printable science worksheet for students in Grades 6–12. Its 12 multiple-choice questions check whether students can identify the variables compared in each gas law, recall the required Kelvin temperature scale for Charles’s Law, select the correct formulas, and identify which variable remains constant. The worksheet also reinforces the difference between direct and inverse proportionality. Students apply those relationships conceptually by predicting how temperature changes when volume changes at constant pressure and how pressure changes when volume changes in Boyle’s Law. The included answer key supports quick review, independent practice, or an introductory check of students’ understanding before more advanced gas-law calculations.

This 12-question multiple-choice worksheet helps students distinguish Charles’s Law, which compares volume and temperature at constant pressure, from Boyle’s Law, which compares pressure and volume. Students identify the Kelvin requirement and correct formulas, then use direct and inverse relationships to predict how one gas variable changes when another changes.
Introduce the worksheet by having students sort the two laws by variables, then discuss the constant in each relationship before they begin the multiple-choice questions. Ask students to justify their choices about doubling volume in Charles’s Law and increasing pressure or volume in Boyle’s Law, using the formulas and proportionality terms as evidence.
Watch for students choosing Celsius instead of Kelvin, reversing the Charles’s Law formula, or treating its volume–temperature relationship as inverse rather than direct. Students may also confuse Boyle’s pressure–volume relationship with a direct one, select the wrong formula, or miss that pressure and volume move in opposite directions.
Wayground provides this worksheet as a printable PDF and as a digital quiz, with a complete answer key for all 12 multiple-choice questions. You can grade printable submissions by scanning student work with the Wayground for Teachers app, or use the digital quiz to review responses in Wayground.
