Lab: Charles's Law Answers

The top of the syringe is a circle. You need to compute its area for use in later computations of pressure values. Start by using a ruler to measure the diameter. Estimate to the nearest 0.01 cm. cm

Divide by two to find the radius. Maintain significant figures. cm

Substitute the radius into the formula to find the area of the top of the syringe. Maintain significant figures. cm²

Measure the mass to the nearest gram (1 g). g

In this experiment, you will measure all masses in kilograms. Convert the book’s mass to kilograms. kg

Total the mass on the syringe. Record it in the correct row of the data table. kg

Calculate the pressure using the formulaP = 1.03 + Mass on Syringe/Area of Top of SyringePressure: kg/cm²

Measure the volume of the gas in the syringe. Estimate it to the nearest 0.5 mL. mL

Compute the product of P • V.
