What are two physical changes that cooling a hot substance may result in?
Cooling a hot substance may result in the condensation of its gaseous state into a liquid state. It may also cause the solidification of a liquid into a solid form as the substance loses its heat energy and transitions to a lower temperature state.
How could you determine the specific heat of a sample of a solid substance that does not react with water?
One way to determine the specific heat of a solid substance that does not react with water is by using the method of calorimetry. This involves measuring the temperature change of the substance when it is heated or cooled, and using the formula q = mcΔT to calculate its specific heat capacity, where q is the heat added or lost, m is the mass of the substance, c is the specific heat capacity, and ΔT is the temperature change.
Why is it necessary to weigh an anhydrous substance with a cover on?
Weighing an anhydrous substance with a cover on helps prevent moisture from the air from being absorbed by the substance, which could affect the accuracy of the measurement. By keeping the cover on during weighing, the substance is protected from exposure to moisture or other contaminants.
Is a solid a compound or an element?
A solid can be either a compound or an element. A compound is a substance made of two or more elements chemically combined, like salt (sodium chloride). An element, on the other hand, is a substance made of only one type of atom, like iron or oxygen.

What substance on earth is not a liquid solid or gas?
Fire. It is a plasma and could be any of the 3.
A hard substance that has a high melting point and is a poor conductor of electricity in the solid phase could be?
It Could be Boron
Which substance is a solid?
anything that's not a liquid or gas. it could be a book, phone, computer, etc.
What most likely caused the substance to be solid in the second picture?
The substance in the second picture is likely solid due to a decrease in temperature or an increase in pressure, which can lead to a phase change from liquid or gas to solid. Additionally, if the substance is a solution, the evaporation of a solvent could have resulted in crystallization, leaving behind solid particles. These conditions promote the molecules to arrange themselves into a fixed structure, resulting in a solid form.
Could expansion when a substance is heated or contraction when a substance is coooled cause problems?
Yes, the thermal expansion is very important in physics and technology.
Does a substance that is insoluble have to be a solid?
Actually, an insoluble substance does not have to be a solid. Think of cooking oil. It is a liquid, however, it does not dissolve in water. Hope I helped!=) -Razzi (Delilah Hope) No an insoluble substance can be solid, liquid or gas. However, trying to dissolve one liquid into another (mixing them together) is referred to as immiscible. Mostly insoluble refers to dissolving a solid or gas into a liquid.
Where can I get substance abuse training?
One thing that you could do for free counseling on substance abuse would be to talk to the preacher at a local church. This is what my dad did when he had problems.
Is fuel a gas?
A fuel is any substance used as a potential energy source. It could be a solid, liquid, or gas.
What are the industrial safety problems?
Industrial safety problems are problems that could result in injury to industrial workers or damage to industrial property. They include fire and explosion hazards, sharp edges, falling, hot parts and materials, heavy parts movement, and much more.
