What tool is used to measure the volume of an irregularly-shaped solid?
-
Ruler
-
Graduated cylinder
-
Balance
-
Thermometer
Correct Answer
A. Graduated cylinderExplanation
A graduated cylinder is used to measure the volume of an irregularly-shaped solid because it has markings on its side that indicate the volume of liquid it contains. By placing the solid in the graduated cylinder and measuring the change in liquid volume, one can determine the volume of the solid. A ruler would not be suitable for measuring the volume of an irregularly-shaped solid as it only measures length, not volume. A balance is used to measure the mass of an object, not its volume. A thermometer measures temperature, which is unrelated to volume.Rate this question:

Why it
Correct Answer
A. WhatExplanation
Scientific Laws tell us "what" happened. Scientific laws are general statements that describe how the natural world behaves under certain conditions. They summarize observations and experiments and provide a framework for understanding and predicting phenomena. These laws explain the "what" of a particular event or phenomenon, describing the relationships between variables and the outcomes observed in experiments or observations. They do not necessarily explain the "why" or the underlying mechanisms behind the observed phenomena, but they provide a reliable description of what occurs.Rate this question:

Check the three types of variables we have in experimental design:
-
Dependent
-
Independent
-
Control
-
Smooth
Correct Answer(s)
A. Dependent
A. Independent
A. ControlExplanation
The given correct answer includes three types of variables in experimental design: dependent, independent, and control. Dependent variables are the ones that are being measured or observed in an experiment and are expected to change as a result of the independent variable. Independent variables are manipulated or controlled by the researcher to test their effect on the dependent variable. Control variables are kept constant throughout the experiment to eliminate any other factors that could influence the results. The term "smooth" does not fit into the three types of variables in experimental design.Rate this question:
