Question

You have been given an orange liquid and told to describe its properties. What methods would you use to observe, measure, and describe the physical properties of this orange liquid without changing it?

Answer 1

From observing the liquid you can get the following information: the color, the state of matter, the smell  and the fluidity [that is, does it flow freely or it is viscous in nature].
By measuring, you can get the volume of the liquid using measuring cylinder. You can also determine the temperature of the liquid at the room temperature using thermometer.
