The Agawam High School band is playing some lively marches while the coaches are giving pep talks to their respective football squads. Although it is September, it is unseasonably hot (88ºF/31ºC) and the band uniforms are wool. Suddenly, Harry the tuba player becomes light-headed and faints. Explain what happened.

Charles' Law
Change the simulation to "Charles' Law" by clicking the tab at the top of the screen it will be shown in white. You should see
the picture below on your screen.
1. Which one of the three variables: Pressure, Volume or Temperature cannot be changed in Charles' Law? This varlable
is considered a constant.
1. a. Using the Temperature controls, increase the temperature of the gas. What changes do you observe in the behavlor
of the particles of the gas while the temperature is increased?
b. Continue to increase the temperature value until T, = 44K. Using the equation for Charles' law, calculate the volume of
the gas at this increased temperature. Check your final answer for part b by clicking the calculate button next to V2:
c. Based on the final value calculated in part b) is Charles' law considered a direct or an indirect relationship between the
variables? Explain your cholce with reasoning.
