Temperature is one unit of measurement. Which tool is used to measure temperature?
Correct Answer
B. Thermometer
Explanation
A thermometer is used to measure temperature. It is a tool that consists of a narrow glass tube with a bulb at one end. The bulb contains a liquid, usually mercury or alcohol, which expands or contracts based on the temperature. As the liquid expands or contracts, it moves up or down the tube, indicating the temperature. Thermometers are commonly used in various settings, including weather forecasting, medical applications, and household use.

This tool can be used to measure length and area. Check all that apply.
Correct Answer(s)
A. Meterstick
B. ruler
Explanation
A meterstick and a ruler are both tools that can be used to measure length and area. A meterstick is a long, slender measuring tool typically one meter in length, while a ruler is a shorter measuring tool usually around 30 centimeters long. Both of these tools have markings that allow for accurate measurements of length and can also be used to measure the dimensions of a two-dimensional shape, which determines its area. Therefore, the correct answer is meterstick and ruler.
