Conduction is the mode of transfer of heat in solids. "Burns produced by steam is severe than that prduced by boiling water" Why?

Conduction is the mode of transfer of heat in solids. Write the unit of thermal conductivity.

The blister caused by steam is more severe than the same caused by boil- ing water at the same temperature. Do you agree with the statement? Jusilfy the statement on the basis of physical change

Why hard water is not used in industrial boilers for producing steam?

An orange solid. 'X' on heating givés a green rešidue 'Y', water vapours and a colourless gas Z. The gas 'Z' in dry conditions is passed over heated 'Mg' to give à solid 'W' which further reacts, with water to produce gas E which gives dense white fumes with HCl. Identify 'X, Y_ Z W. E

Two accidents are happened. The first one with water at 100°C and the second one with steam at 100°C . Which is dangerous burn due to water at 100°C , and burn due to steam at 100°C . Why?

Ice melts below 0^(@)C when pressure is applied because : pressure generates heat, chemical bonds breaks under pressure, ice is less denser than water, ice is not a true solid

From the following statements Choose those applicable to covalent compounds. • Dissolves in organic compounds • Dissolves in water • High melting and boiling point. • Found in solid liquid and gaseous states. • Conducts electricity.
