1. What is the state of matter of each of these materials at room temperature? a) gold b) gasoline c) oxygen d) olive oil e) mercury (found in thermometers) f) aluminum

a) gold - Solid

b) gasoline - liquid

c) oxygen - gaseous

d) olive oil - liquid

e) mercury (found in thermometers) - liquid

f) aluminum - solid

Explanation:

Matter exists in three states viz: solid, gas and liquid. Note that, room temperature is a neither hot or cold temperature, which is about 20-23°C.

A) Gold is a transition metal with the symbol Au. At a room temperature, Gold, like most metals are found as SOLIDS.

B) Gasoline is a liquid mixture of refined hydrocarbons majorly used as fuels.

C) Oxygen is a chemical element with symbol O. It is a constituent of natural air, which is a mixture of different gases including oxygen. Hence, at room temperature, Oxygen is a gas.

D) Olive oil is a vegetable oil got from olives. It is composed of fats and it's a liquid at room temperature.

E) Mercury is an element with symbol Hg. It is the only metallic element found naturally (at room temperature) as a liquid. It is used in thermometers.

F) Aluminum is another chemical element with symbol Al. It is a lustrous metal that occurs as a Solid in room temperature.
