A student is investigating temperature changes in reactions involving acids. Name a piece of equipment they could use to measure out a set volume of acid. Enteranswer

## Step 1: Understand the problemThe question asks about a piece of equipment that a student can use to measure out a set volume of acid while investigating temperature changes in reactions involving acids.## Step 2: Identify the relevant equipmentWhen working with acids and measuring precise volumes, a common piece of equipment used in chemistry laboratories is a volumetric flask or a graduated cylinder.### \textbf{Volumetric Flask}: A volumetric flask is a calibrated glass container with a flat bottom and a long neck. It is designed to accurately measure and contain a specific volume of liquid. Volumetric flasks are available in various sizes, such as 100 mL, 250 mL, 500 mL, and 1000 mL.### \textbf{Graduated Cylinder}: A graduated cylinder is a cylindrical container made of glass or plastic, with graduated markings along the side to indicate the volume. Graduated cylinders are available in different sizes, ranging from a few milliliters to several liters, and are commonly used to measure and transfer liquid volumes.## Step 3: Choose the appropriate equipmentBoth a volumetric flask and a graduated cylinder can be used to measure out a set volume of acid accurately. However, for precise measurements, a volumetric flask is generally preferred due to its higher accuracy and calibration for a specific volume.
