Solid state

Assertion:At low temperature , particles of matter occupy fixed positions and exist in solid state. Reason : Under a given set of conditions of temperature and pressure , the state of a substance depends upon the net effect of thermal energy and intermolecular forces.

Can sodium chloride conduct eletricity in the solid state ? (A)Solids do not conduct electricity. (B)The ions of NaCl become mobile only in molten state and are not free to move in solid state. (C)The crystalline structure does not have ions. (D)When a bond is formed between ions they lose their charges.

(a). What is the hybrid state of Be in BeCl_(2) in vapour state. What will be the change in the hybrid state of BeCl_(2) in the solid state? (b). Draw the structure of (i) BeCl_(2) (vapour state) and (ii) BeCl_(2) (solid state). (c ). Why do halides and hydrides of beryllium polymerise?

Identify the type of cyrstalline solid based on the following properties : (a) Conducts electricity in the molten state but in the solid state. (b) Very hard with melting point and acts as electrical insulator. (c) Conducts electricity in the solid state, malleable and ductile.

A solid substance 'A' is very hard and electrical insulator both in the solid state as well as in molten state. It has also very high melting point. Is the solid metal like silver or network solid like silicon carbide (SiC) ?

Matter exists in two states - solids and liquids.

Which of the following refers to the change of state from solid to liquid?

Magnetically ordered solids transform to paramagnetic state upon heating. Explain.

As a physicist, you put heat into a 500 g solid sample at the rate of 10.0 kJ//min , while recording its temperature as a function of time. You plot your data and obtain the graph shown in figure. . (a) What is the latent heat of fusion for this solid? (b) What is the specific heat of solid state of the material?

(a) Conversion of solid of vapour is called sublimation . Name the term used to denote the conversion of vapour to solid. (b) Conversion of solid state to liquid is called fusion, what is meant by latent heat of fusion?
