That's physical properties, is it a chunk that you can lift up then its a solid, if it can be poured it's either a liquid or a solid ground into grains.

∙ 15y agoRoom temp is about 68 F or 20 C, if the melting point is below room temp it is not a solid at room temp. If the boiling point is above room temp then it is not a gas so it has to be a liquid at room temp.
Wiki User
∙ 13y agoThe temperature of the room is around 25 ºC or ~80 ºF, if the melting point is greater than this, then the substance is a solid.
If the melting point is less than room temperature but the boiling point is greater than the temperature of the room then the substance is a liquid and if the boiling pt is greater than the room or reference temperature then the substance is a gas.

Wiki User
∙ 10y agoThere is not really enough information to asnwer this question. It would depend on the material. Each material has a different solid melting point, liquid freezing or boiling point, and gas condensing or freezing point.

∙ 14y agoIf it has a definite volume but no defenite shape, it's a liquid.
If it has a definite shape and volume it's a solid.

What are two ways that you could tell the difference between pure water and salt water?
Taste Smell Melting Point Boiling Point Density Residue after it evaporates
Explain why the boiling point and the melting point can be used to help identify substances?
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.
What information about the compound is not part of the chemical formula?
The information that isn't given in the formula is that it doesn't tell you the position of the atoms.
When ice melts why can you tell there is not a chemical change?
Melting is not a chemical change because the chemical formula of water remain unchanged.
When finding melting points why does heating the water slowly give more accurate results?
If you're trying to find the melting point of water, you may have confused your terms. A given substance's melting point is basically the point between solid and liquid phases, whereas the boiling point is the point between liquid and gas phases. I may have misunderstood the question... To answer your question with the assumption that you are trying to find the melting point of a solid, it does help to heat the solid (or, if you meant that you are heating a water bath that subsequently heats a solid held in a container in the water bath in which case you didn't confuse your terms!) slowly because in so doing, with smaller increments in temperature, you will be able to tell more accurately the temperature at which melting occurred. While we may not feel it in daily life, there is a fairly big range between two sequencial degree markings. 90.0, 90.1, 90.2 and so on may not feel different to us, but to a chemical, it may "feel" different. If you measure the MP in ten degree markings, you might be able to tell that the solid melted around 100 degrees or 110 degrees. But if you use smaller markings, say 1 degree in size, you can more accurately tell that the substance melted at 106 degrees. Increased precision in measuring instruments might show that, in fact, the substance melted at 106.43 degrees. So, if you heat the water slowly (depends on your equipment), at 0.2 degree (C) increments, let's say, then you'll be able to see that the substance melted at 106.4 degrees. But if you heat it quickly, such as at 1 degree increments, then even if the substance melted at 106.43 degrees, you could only approximate the MP at 106 or 107 degrees. I hope thatmakes sense, though it's just part of the answer.
How can you tell that the melting of ice cube is a physical change?
You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.
What is the shape of the graph at the melting and freezing points of water what does this shape tell you about the temperature?
you got to find out yourself
Could you tell me 3 examples from everyday life which show the affect of pressure and impurities on the melting and boiling points?
hey i really need help, can u answer the Question

What baking equipment can tell when water is boiling?
lol wow you dont need a piece of equipment to tell when water is boiling... you just watch the water as it heats up and when it starts to bubble its boiling... Ta -dah!
If more than one phase of water is present what does it tell you about the temperature?
The temperature will be either the boiling point (if liquid and vapor is present) or it will be the melting/freezing point (if liquid and ice is present)
Is the boiling point of water higher than the boiling point of water?
physiological answers tell us that In neurology water may be boiling at a lower substantial rate then non water water.
How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
Tell you three characteristics of formaldehyde?
Three characteristics of formaldehyde is melting point(−92 °C) , boiling point(−21 °C), and it is a colorless gas.
What can you tell about methane (CH4) from its molecular formula?
It is a saturated hydrocarbon. It is a covalent compound and has all properties which are identical to simple covalent compounds. Low boiling and melting points, soluble in organic solvents (most simple covalent compounds are soluble in organic solvent), insoluble in water and does not conduct electricity as in does not have free ions.Its tetrahedral geometry makes it non-polar.It contains four hydrogen atoms
What are some examples of physical properties scientist use to tell the differences between substances?
Melting point and boiling point are two physical properties that can be used to tell the difference between substances.
