3. Which statement is true about a triple beam balance and a spring scale?
A triple beam balance is used to measure the weight of an object, and a spring scale is used to measure the mass of an object.
A triple beam balance is used to measure the mass of an object, and a spring scale is used to measure the weight of an object.
Both a triple beam balance and a spring scale are used to measure the weight of an object.
Both a triple beam balance and a spring scale are used to measure the mass of an object.
4. In a laboratory classroom, what should you do if you get chemicals into your eyes?
Go home to shower
Wipe the chemicals off your face
Put safety goggles on so it doesn't happen again
Locate and use the eye/face wash station

To find the answers to the questions:
1. To determine which statement is true about a microscope and spectroscope, you can start by understanding the basic functions of each tool. A microscope is generally used to view small objects, such as cells or microorganisms, by magnifying them. On the other hand, a spectroscope is used to observe and analyze light spectra emitted or absorbed by elements or compounds. By comparing the purposes of these two tools, it becomes clear that "A microscope is used to view very small objects, and a spectroscope is used to view the spectra of elements" is the correct statement.
2. To identify the tool used to measure relative humidity in the atmosphere, you can consider the options provided. A psychrometer is a device specifically designed for measuring relative humidity. On the contrary, a thermometer measures temperature, an anemometer measures wind speed, and a barometer measures atmospheric pressure. Therefore, the correct option is "psychrometer."
3. Comparing a triple beam balance and a spring scale, we can differentiate their functions to determine the true statement. A triple beam balance measures the mass of an object using the gravitational force acting on it, while a spring scale measures the weight of an object by the force applied to the spring. Since mass and weight are different properties, "A triple beam balance is used to measure the mass of an object, and a spring scale is used to measure the weight of an object" is the correct statement.
4. To understand the appropriate course of action if chemicals get into your eyes in a laboratory classroom, it is crucial to prioritize safety. In this scenario, the best choice would be to immediately locate and use the eye/face wash station. This safety equipment is specifically designed for rinsing out harmful substances from your eyes. The other options mentioned, such as wiping the chemicals off your face or putting safety goggles on, might not effectively eliminate the risk and should be avoided in a situation where chemicals have entered your eyes.
