Solution

When metal reacts with hot or cold water it forms metal hydroxides and when it reacts with steam (water_gas) they form metal oxides
for ex.,
$W i t h c o l d w a t e r h y d r o x i d e s a r e f o r m e d w i t h t h e l i b e r a t i o n o f h y d r o g e n 2 N a + 2 H_{2} O \to 2 N a O H + H_{2} W i t h h o t w a t e r h y d r o x i d e s a r e f o r m e d w i t h t h e l i b e r a t i o n o f h y d r o g e n M g + 2 H_{2} O \to M g (O H)_{2} + H_{2} W i t h s t e a m o x i d e s a r e f o r m e d w i t h t h e l i b e r a t i o n o f h y d r o g e n M g + H_{2} O \to M g O + H_{2}$
