Answer: moles
Explanation: Boyle's law:
Boyle's law stated that volume and pressure are inversely proportional to each others by keeping the number of moles and temperature constant.
Mathematical expression:
P₁V₁ = P₂V₂ (n and T are constant)
Charles's law:
Charles's law stated that temperature and volume are directly related related to each others by keeping number of moles and pressure constant.
Mathematical expression:
V₁/T₁ = V₂ /T₂ (n and P are constant)
Gay-Lussac's law:
This law stated that pressure of gas is directly related to its temperature by keeping the number of moles and volume constant.
Mathematical expression:
P₁/T₁ = P₂ /T₂ (n and V are constant)
The element that has the greatest attraction for sulfur electrons is I (Iodine)
The molarity of H2SO4 is the number of moles in 1 L of solution.
The molarity is 2.0 mol/L
This means that there should be 2 moles in a 1 L solution to make up this molarity.
In this case we need to make up a 5 L solutions with that molarity. Then the amount of moles required are - 2 mol/L x 5 L = 10 mol
The speed is 7,350km that's the speed of the car
Answer: Option (c) is the correct answer.
Explanation:
Energy that is acquired by the molecules of a substance due to their motion is known as kinetic energy.
For example, when we heat water in excess then it starts to boil and it changes into vapors.
Hence, when molecules of a liquid gain kinetic energy then they start to collide rapidly with each other. As a result, molecules move away from each other and there occurs decrease in force of attraction between the molecules. This leads to change of liquid state into vapor or gaseous state.
Thus, we can conclude that the statement they move fast enough to overcome the forces of attraction that hold them together, becoming a gas, best explains what happens when the kinetic energy of particles in a liquid state increases.
