Measuring Mass per Unit Area of a Soft Blanket

In summary, the conversation involves a question about finding the mass per unit area of a blanket. The process involves finding the mass and area of the blanket and then using the formula "mass/area" to calculate the mass per unit area. The softness of the blanket does not affect this calculation.

hi

I'm doing a question involving the mass of a blanket ...
I just need to know the following :

could somebody please tell me :

what it means by mass per unit area ?

and for a blanket, how is the mass/unit area measured because the blanket is soft ?

Ask yourself, what is the mass of the blanket? What is the Area of the blanket? Can you think of a way to get the mass per unit area? It does not matter if the blanket is hard or soft, you would do the same thing to get the mass per unit area of a piece of a thin wood.

I'm not sure how to measure the mass of the blanket ?

or to get mass per unit area ?
 
  • #4
Can someone please explain why it doesn't matter how soft the blanket is ?

and how to get the mass per unit area ?

THANX

Generally to get the mass of something you weigh it, convert lbs to Kg you have the mass. Measure the blanket to find its area.

compute

[tex] \frac {Mass} {Area} [/tex] to get mass per unit area.

"Softness" simply does not enter into it.
 

1. What is the definition of mass per unit area?

Mass per unit area, also known as surface density or areal density, is the measure of the mass of a substance per unit of area. It is typically expressed in units of grams per square meter (g/m²) or kilograms per square meter (kg/m²).

2. How is mass per unit area different from density?

Mass per unit area and density are related but different concepts. Density is the measure of the mass of a substance per unit of volume, while mass per unit area is the measure of the mass per unit of surface area. Density is typically expressed in units of grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

3. What are some common applications of mass per unit area?

Mass per unit area is commonly used in different fields of science and engineering, such as material science, geology, and physics. It is also used in industries like textiles, papermaking, and packaging to measure the weight of materials per unit area.

4. How do you calculate mass per unit area?

The formula for calculating mass per unit area is: Mass per unit area = Mass / Area. The mass is measured in units of grams (g) or kilograms (kg), and the area is measured in units of square meters (m²). For example, if a piece of paper weighs 10 grams and has an area of 0.1 square meters, the mass per unit area would be 10 g / 0.1 m² = 100 g/m².

5. What factors can affect the mass per unit area of a substance?

The mass per unit area of a substance can be affected by various factors, such as the type and density of the material, the temperature and pressure, and the presence of any impurities or additives. Other factors like the thickness and surface area of the material can also impact its mass per unit area.
