Question

From the above substances which ones are in liquid state ?​

Answer 1

Answer:

Only two elements are liquid at standard conditions for temperature and pressure: mercury and bromine. Four more elements have melting points slightly above room temperature: francium, caesium, gallium and rubidium.

Answer 2

Answer:

Question: which ones are in a liquid state?​

A)Steel

B)Cardboard

C)Water

D)Iron

option c is correct.

Explanation:

Almost all materials can exist in a liquid state however it relies upon the conditions. Substances that might be gassed at room temperature may be liquified via way of means of cooling them beneath pressure. An instance of that is liquid oxygen and liquid nitrogen.

Most solids may become liquids via way of means of heating them. Consider ice melting to water at 0C or wax being melted at a temperature barely above room temperature. Most stable metals may be melted with sufficient warmth. Even glass may be melted right into a liquid at very excessive temperatures. The exception is some solids that sublime. Sublimation is the procedure of a stable turning immediately right into a vapor without melting. Dry ice is an instance. Dry ice is stable carbon dioxide. Shippers like to apply it for preserving applications frozen. A block of dry ice will hold the package frozen via way of means of slowly subliming. The sublimation procedure absorbs warmth and releases carbon dioxide. Carbon dioxide is a fuel line to leak out of the package leaving the contents dry but frozen.

Then you've got got a variety of liquids which might be liquid at room temperature. Examples are water, gasoline, ethyl alcohol, vegetable oil, benzene, etc.
