True or False
Gold is a good conductor of heat
One of the best conductors of electricity is
copper.
Sonorous is a characteristic of metals.
We use non-metals to make bells because
they ring when they are hit.
The only liquid metal at room temperature
(250C) is Bromine.
Carbon is a non-metal and is solid at room
temperature.
Non-metals are not shiny. They are dull.
All the metals are solids at room temperature
Steel is an element.
There are magnetic metals: iron, cobalt and
nickel.
Alloy is a mixture of metals.
Steel is an alloy which contains mostly iron.
5. Metals are malleable; Give an example of such a metal that we use in our kitchen.
