The actual mass of a 1 cm² piece of copy paper is determined as 0.0074 g.
<h3>Area of the sheet of paper in square centimeters</h3>
Area = Length x Width
Area = (11 x 2.54 cm) x (8.5 x 2.54 cm)
Area = 603.22 cm²
<h3>Actual mass of the sheet of paper</h3>
Mass = area density/area
Mass = (4.5 gcm²)/(603.22 cm²)
Mass = 0.0074 g
The complete question is below:
A sheet of 8.5 inch by 11inch paper has a mass of 4.50 grams one square centimeter , 1cm2 of that sheet of paper will have a mass closets to ____grams ( (hint use 1inch = 2.54 centimeters and area = length times)

Answer:
The temperature of the cooler substance was close to the room temperature. Therefore, the system experienced less change
Explanation:
Generally, in a closed system containing two bodies at different temperatures, there is a flow of heat energy from the body at a higher temperature to the body at a lower temperature. The effect is more significant when there is a large temperature difference between the bodies. However, if the temperature difference is small or insignificant, the change will be less.
The conservation of the mass of fluid through two sections (be they A1 and A2) of a conduit (pipe) or current tube establishes that the mass that enters is equal to the mass that exits. Mathematically the input flow must be the same as the output flow,
The definition of flow is given by
Where
V = Velocity
A = Area
The units of the flow of flow are cubic meters per second, that is to say that if there is a continuity, the volume of input must be the same as that of output, what changes if the sections are modified are the proportions of speed.
In this way
