Kinetic energy of the particles is the measure of energy of the molecules when they are in motion. Kinetic energy is increased when phase change occurs from solid to liquid to gas. Solid has a rigid state which disables the particles to move unlike that in gas and liquid state where liquids can move more because of the spaces in between them.
Answer:
Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.

In H4SiO4, the mole ratio of carbon to hydrogen to oxygen is the same as described in the question. Therefore H4SiO4 is the empirical formula
I hope this helps you!!
Answer:
Liquid: 38.7 g x 1 ml/0.865 g = ml of liquid
Vol of solid = 80.0 ml - ml of liquid
mass of solid = vol of solid x 2.75 g/ml
(100. g)
Explanation:
you can use this as a eg for this question
