The melting point of four substances are given in bracket, then the attraction forces in a solid are more in case of
Ice `(273K)`
`NaF` `(1270K)`
Phosphorus `(317K)`
Naphthalene `(353K)`

The melting point of gold is 1064^(@)C . Express this in ""^(@)F and K.

Arrange the following according to the instruction given in bracket : K, Pb, Ca, Zn [In the increasing order of reactivity].

Which of the following is relatively stronger acid? K, values are given in brackets

Correct the statements : Boiling point of water is 273 K.

Why is ice at 273k more effective in cooling than water at the same temperature?

IF the melting point of ice is 273 K and molar enthalpy of usion for ice = 6.0 kJ mol^(-1) , the change in entropy for the fusion of 1 mole of ice will be

Arrange the following as per the instruction given in the brackets: Na, K, Li (Increasing atomic size)

Draw a perpendicular to a given line segment though a point K on the line segment .

The melting point of a solid is 300K and its latent heat of fusion is 600 cal mol^(-1) . The entropy change for the fusion of 1 mole of the solid ( in cal K^(-1)) at the same tempertre would be :
