<u>Answer:</u> The mass of plastic sheet is 
<u>Explanation:</u>
The plastic sheet is in the form of cuboid. To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 10.0 m = 1000 cm (Conversion factor: 1 m = 100 cm)
b = breadth of cuboid = 1.0 m = 100 cm
h = height of cuboid = 1 cm
Putting values in above equation, we get:
To calculate mass of a substance, we use the equation:
We are given:
Density of plastic sheet = 
Volume of plastic sheet = 
Putting values in equation 1, we get:
Hence, the mass of plastic sheet is
C. Solid
Although molarity is commonly used to express concentrations for reactions in solution or for titrations, it does have one drawback—molarity is the number of moles of solute divided by the volume of the solution, and the volume of a solution depends on its density, which is a function of temperature.

It has been banned in Canada, China, and the EU due to concerns about its potential links to several health issues including: kidney damage, nervous system damage, cancer, thyroid issues and gastrointestinal distress.</span>
The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.
- A beaker with an open top contains a sample of liquid. It exposes this sample to light.
- That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
- Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
- This can be done by applying a heat balance.
