How does resistance of a metal vary with temperature?

In general it is observed that the rate of a chemical reaction doubles with every 10^@ rise in temperature. If the generalisation holds for a reaction in the temperature range 295K to 305K, what would be the value of activation energy for the reaction?

What is the value of specific heat of water in l.S. units? Does it vary with temperature?

What is valency? How does it vary along the period?

How does surface tention change with temperature?
