Most specific heat capacities are found by combining a substance with another with a known specific heat usually water. But How do chemists know the specific heat capacity of water in the first place?

The specific heat capacity of water was initially determined through experiments involving measuring the temperature change when a known amount of water absorbs a certain amount of heat. The relationship between the heat absorbed, temperature change, and mass of water was used to calculate the specific heat capacity of water. This value has been confirmed and refined over time through numerous experiments and calculations.

What is the difference between not clean substance and not pure substance?
Chemists prefer the expression pure substance.
Why do chemists classify CHCl3 as an organic substance even though the substance is not produced by organisms?
Because it's a carbon based compound.
What are the two types of changes that chemists are primarily interested in?
Chemists are primarily interested in studying physical changes, which involve a change in appearance or state of matter without a change in composition, and chemical changes, which involve a change in the chemical composition of a substance.
What unit do chemists use to measure the amount of substance since they cant ohysically count the pieces in that substance?
They measure the mass, usually in grams or milligrams, but any "type" of gram is possible. For example, the molar mass of a substance is the mass of one mole of that substance in grams. We can't count the individual particles, but we can measure the molar mass on a balance.
How do chemists express the degree of acidity or basicity of a substances?
Chemists use the pH scale to express the degree of acidity or basicity of a substance. The pH scale ranges from 0 to 14, with values below 7 indicating acidity, 7 being neutral, and values above 7 indicating basicity. pH is a logarithmic scale, so each whole number change represents a tenfold difference in the acidity or basicity of the substance.
What is the difference between not clean substance and not pure substance?
Chemists prefer the expression pure substance.
Why do chemists classify CHCl3 as an organic substance even though the substance is not produced by organisms?
Because it's a carbon based compound.
Can you buy chloroform from your local chemists?
No, chloroform is a controlled substance and can only be obtained with special permissions for research or medical purposes. It is not sold over the counter at local chemists.
What is substance was developed by chemists?
Aspirin was developed by chemists in the 19th century. It is derived from willow bark and is commonly used as a pain reliever and anti-inflammatory medication.
What is the possessive noun for chemists?
The possessive noun for "chemists" is "chemists'."
Did chemists believe in the phlogiston theory?
Yes, chemists believed in the phlogiston theory in the 17th and 18th centuries. It was thought that when substances burned, they released a substance called phlogiston. However, the theory was eventually disproven with the development of modern chemistry.
How composites are use?
it is useful because when combining the useful properties of two or more substances in a composite, chemists can make new material that works better than either one alone
What is the plural for chemists?
Its just chemists.
What did early chemists discover about reactions involving the combination of gases?
Early chemists discovered that when gases react with one another, they do so in simple whole-number ratios by volume, known as the law of combining volumes. This led to the development of the law of multiple proportions, which states that when elements can combine to form different compounds, the masses of one element that combine with a fixed mass of the other element are in ratios of small whole numbers.
How are mass and capacity used in real life?
Mass is used for scientists/ chemists. They are trying to find the mass of the smallest things like atoms, molecules, and other elementary particles. Capacity is used in public places like gymnasiums or buses.
What are the two types of changes that chemists are primarily interested in?
Chemists are primarily interested in studying physical changes, which involve a change in appearance or state of matter without a change in composition, and chemical changes, which involve a change in the chemical composition of a substance.
Why do chemists use stoichiometry?
Chemists use stoichiometry to determine the quantities of reactants and products in a chemical reaction based on the balanced equation. This helps in predicting how much of each substance is needed or produced, aiding in the efficiency of reactions. Stoichiometry also allows chemists to evaluate the purity of products or the extent of a reaction.
