Is Talc an element?
No, talcom is not an element. To be an element, a substance must have all the same type of atom. Once it has this, it can go on the Periodic Table. So, as talcom has many different types of atom in it, it's not an element.
What is the similarities between water vapour and steam?
Both are same.
What is liquid hydrogen made of?
Hydrogen. Just like liquid steam is made of water molecules - the same stuff but in a different form.
Why are average summer temperatures in the southern hemisphere cooler than average summer temperatures in the northern hemisphere?
Probably because the southern hemisphere has more water than the northern hemisphere. It takes more heat to raise a given mass of water a certain number of degrees than to raise the same mass of any other substance the same number of degrees.
Are Xfactor and Britains got talent the same show?
The concept is the same and they are part of the same franchise but ultimately they are two different shows, in different countries, with different judges.
Why can't we use the same substance to make everything?
Water is a substance!!!! So how could you make houses with water. How could you make clothes with water. We need different substances for different things. !!!!!
Is milk to coffee as water is to ice?
No. Ice and water are the same substance (they're both water); the only difference is the state of matter the two are in. Milk and coffee are different substances and they're in the same state of matter.
What are two of the same substances that have the same mass but different volumes?
First of all, there's no such thing as the mass of a substance, or the volume of a substance. You can have 0.01 kilogram of water or 10,000 kilograms of water. It only depends on how much you decide to scoop out of the bucket. The water itself has no characteristic mass. Similarly, you can have 1 milliliter or 1 cubic kilometer of potato salad. It only depends on how much you buy at the deli. The potato salad itself has no characteristic volume. If you measure out the same mass of two different substances, then the sample of the substance with the greater density will have less volume. If you measure out the same volume of two different substances, then the sample of the substance with the greater density will have more mass.
Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
There is a formula in physics ΔQ=m*c*ΔT, where m is the mass of the substance you are heating, ΔQ is the heat you supply to the substance, c is the specific heat which has a different value for different substances and ΔT is the change in temperature. If your substances are different and they have the same mass then by supplying the same amount of heat the change in temperature will be different.
Do objects of the same size and shape have the same mass?
No, not unless they are made of the same substance. Different substances have different densities, which means that the same volumes will have different masses.
Can the melting and freezing point of a substance be the same?
For water and some other substances, the answer is 'Yes'.
The attraction among molecules of different substances is called?
An attraction between substances of the same kind is called cohesion. However, if it occurs in water, then it is known as capillary action.
Why is it that two different substances that have the same masses can have differen weights?
Two different substances that have the same mass will also have the same weight if they are in the same location. Weight is the force of gravity acting on the mass of a body (or substance). The force of gravity decreases the further you are from the center of the earth, so it is possible for two substances with the same mass to have different weights if they are at different distances from the center of the earth.
Is a substance the same as an ingredient?
A substance can be an ingredient, but not all substances are ingredients.
Is dirt a heterogeneous or homogeneous substance?
Heterogeneous because it contains many different substances and is not always the same in composition.
Does the heating of water add substances to it?
no, it will not add substances but may or will evaporate just giving the water in a different form but keeping its same properties .
What boils at what degree Celsius?
This question is too vague to answer: many different substances boil at many different degrees Celsius. In fact the same substance can be made to boil at different temperatures by changing the pressure acting on it.
