For the classification of matter, the incompatible structural term has to be chosen from the given options. Concept Introduction: Atoms of the element are the smallest particle that exists which has the properties of the element. If a group of atoms that is relatively small but bound together means it is known as molecule. Molecules can be classified into various types. Diatomic molecule is a type of molecule that contains two atoms. The two atoms may be of same element or different element. Triatomic molecule is a type of molecule that contains three atoms. The three atoms may be from a same element or different element. This series goes on like this as tetraatomic, pentaatomic molecules etc. If the molecules are to be classified on basis of observation then two types can be given. Homoatomic molecules are the ones that have the atoms of same kind in the molecule. Molecule that contains same type of atoms in it has to be an element. Heteroatomic molecule is the one that contains two or more kinds of atoms in a molecule.

Interpretation Introduction

Interpretation:

For the classification of matter, the incompatible structural term has to be chosen from the given options.

Concept Introduction:

Atoms of the element are the smallest particle that exists which has the properties of the element. If a group of atoms that is relatively small but bound together means it is known as molecule.

Molecules can be classified into various types. Diatomic molecule is a type of molecule that contains two atoms. The two atoms may be of same element or different element. Triatomic molecule is a type of molecule that contains three atoms. The three atoms may be from a same element or different element. This series goes on like this as tetraatomic, pentaatomic molecules etc.

If the molecules are to be classified on basis of observation then two types can be given. Homoatomic molecules are the ones that have the atoms of same kind in the molecule. Molecule that contains same type of atoms in it has to be an element. Heteroatomic molecule is the one that contains two or more kinds of atoms in a molecule.

1. Show that the change in entropy for a fixed amount of ideal gas held at a constant temperature undergoing a volume change is given by the simple equation AS = NkB In Hint: Start with the equation M dS = du + (Œ) dv - Ž (#) an, dU du+av-dN; j=1 Why doesn't the equation for the entropy of an ideal gas depend on the strength of the intermolecular forces for the gas?

2. Make an ice cube at 1 bar pressure by freezing an amount of liquid water that is 2 cm x 2 cm x 2 cm in volume. The density of liquid water at 0 °C is 1.000 g cm³ and the density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason your water pipes burst if they freeze and why you shouldn't forget to take your bottle of pop out of the freezer if you put it in there to try and cool it down faster. A. What is the work of expansion upon freezing? B. Is work done on the system or by the system?
