At room temperature, none of the metals are
a. soft.
b. liquids.
c. malleable.
d. gases.

Answer : At room temperature, none of the metals are gases.

Explanation :

The properties of metals are :

Generally all the metals are solid at room temperature but with exception, the mercury is liquid at room temperature.

Generally all the metals are hard but with the exception, sodium and potassium are soft and easily cut with the knife.

The metals are malleable, ductile, lustrous in nature.

Metals are good conductor or heat and electricity.

Hence, At room temperature, none of the metals are gases.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
