Answer:
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.
i believe the answer is, b. heat energy is continuously added at each step. As energy is added, the molecular motion/kinetic energy increases, and matter changes state. In the last state, plasma, enough energy has been added to cause the atoms to disassociate into ions.
hope this is right! :33
Depends on the height of the mountain. At 2500km (7500ft) it might boil-albeit reluctantly-at 100 degrees Celsius, but higher up not so much.
Volcanic eruptions are caused by earth's internal heat sources.
All the other choices are atmospheric or external earth.
