D is the answer you’re welcome
Answer:
See explanation
Explanation:
According to the kinetic molecular theory, the molecules that compose a gas are in constant random motion.
The temperature of a gas is a measure of the average kinetic energy of the gas molecules.
When the balloon was placed in a hot water bath, the balloon becomes larger because the gas inside the balloon expands. This is because, more kinetic energy is supplied to the molecules of the gas hence they spread out.
When the balloon is placed in cold water, the kinetic energy of the gas molecules in the balloon decreases as temperature decreases hence the balloon shrinks
When a solute is completely dissolved in a solvent, a solution is formed.
Sulfur is the element used to cross-link the hydrocarbon chains when natural rubber undergoes vulcanization.
The invention relates to cross-linking hydrocarbon polymers with aromatic polyazides in the presence of sulfur. It has been discovered that hydrocarbon polymers can be cross-linked when heated with aromatic polyazides.
The density of the object is 0.467 36 g/cm³.
The mass of the object is 389.27 g.
The volume of the object is 832.92 cm³.
Density = mass/volume = 389.27 g/832.92 cm³ = 0.467 36 g/cm³
