Answer:
THE PRESSURE EXERTED BY THE GAS IS THEREFORE 2.88 atm.
Explanation:
Boyle's law states that at constant temperature, the volume of a given mass of gas is inversely proportional to the pressure of the gas.
Mathematically, P1 V1 = P2 V2
Write out the values of the variables given:
P1 = 2.4 atm
V1 = 1.8 L
V2 = 1.5 L
P2 = unknown
Re-arranging the variables by making P2 the subject of the equation, we have:
P2 = P1 V1 / V2
P2 = 2.4 * 1.8 / 1.5
P2 = 2.9=88 atm
Hence, the pressure exerted by the gas is therefore 2.88 atm
2 is the answer iam not sure about it
Yes
Because in SI, the expectation is that area and volume will be expressed in terms of a linear dimension( the metre) or its multiples.
Answer:
Plastics are large organic molecules called polymers.
Explanation:
Plastics can be defined as materials that can be shaped when soft and then hardened to keep their shape. They are synthetic (artificially made) or semi-synthetic, derived from materials found in nature, such as natural gas, oil, coal, minerals, and plants.
As they are derived from natural, organic materials, plastics also consist of organic molecules. Their molecules are very large and long and consist of many repeating subunits. Materials with this type of structure are called polymers.
This is why the second option is the correct one.
