Both a physical and quantitative characteristic to the textile cotton is its seeming light weight. This is an example of both mass and density. A small given of cotton will measure with a low mass. However cotton of high density, compression and quantity can easily be heavy. This lightness comes from cotton fibers being spaced out and thus light.

What type of observation is one that used measurement?
An observation that involves measurement is typically referred to as a quantitative observation. This type of observation involves gathering data that can be expressed using numbers or quantitative values. Examples include measuring the length of a plant or recording the temperature of a liquid.
What property of light best explain your observation?
The observation that light travels in a straight line can be explained by the property of light known as rectilinear propagation. This property states that light travels in a straight line in a homogenous medium.
What observation made with measurement?
An observation made with measurement involves collecting data or numerical information to describe or quantify a phenomenon. It typically involves using tools or instruments to determine the size, quantity, or characteristics of an object or event. This quantitative data can provide a more objective and detailed understanding of the observed phenomena.
What would you use to measure light intensity?
A light meter is typically used to measure light intensity. These devices capture the amount of light in a particular area and provide a quantitative measurement in units such as lux or foot-candles.
Why cotton float on air?
Cotton fibers are light and have air trapped within them, contributing to their buoyancy. Additionally, cotton fibers are hydrophobic, meaning they repel water and are less likely to become waterlogged and sink. This combination of factors allows cotton to float on air.
