Answer: Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. ... Individual particles in liquids and gases have no fixed positions and move chaotically.

Answer;
Water 1.0 g/mL 100°C colorless liquid
Explanation:
thats the answer
This problem is solved using following formula,
Molarity = Moles ÷ Volume of Solution ----- (1)
Data Given;
Volume = 650 mL = 0.65 L
Mass = 63 g
Solution:
First of all calculate moles for given mass,
Moles = Mass ÷ M.mass
Moles = 63 g ÷ 58.4 g.mol⁻¹
Moles = 1.08 mol
Now, putting values of mole and volume in eq. 1,
Molarity = 1.08 mol ÷ 0.65 L
Molarity = 1.66 mol.L⁻¹
If 50.75 g of a gas occupies 10.0 L at STP, 129.3 g of the gas will occupy 25.48 L at STP.
<h3>How to calculate volume?</h3>
The volume of a gas at STP can be calculated using the direct proportion method.
According to this question, 50.75 g of a gas occupies 10.0 L at STP, then 129.3g of the same gas will occupy the following:
= 129.3 × 10/50.75
= 25.48L
Therefore, if 50.75 g of a gas occupies 10.0 L at STP, 129.3 g of the gas will occupy 25.48 L at STP.
