The specific heat of a substance is the energy required to produce a certain change in?
Probably one of the followings:
1 joule of a substance by 1 kelvin
1 kilogram of a substance by 1 kelvin
1 kilogram of a substance by 1 joule
or 1 gram of a substance by 1 degree Fahrenheit
I'm not sure which one exactly, but I'm pretty sure its one of those.
of any substance
specific heat capacity is defined as the amount of heat required to change the temperature of one unit mass of any substance by 1°C or 1K
Specific heat capacity, Cg is the energy needed to raise 1 gram of the substance 1 degree Kelvin (or Celsius)
The units are J g-1 K-1
Energy = Cg x mass x change in T
The specific heat of water is 4.18 J g-1K-1
(Imperial units uses the calorie as a unit of energy.
The specific heat capacity of water is 1.0 cal g-1 K-1)

How much energy is used per kilogram?
The energy usage per kilogram varies depending on the specific energy source or process in question. For example, the energy required to produce a kilogram of steel is different from the energy used to produce a kilogram of rice. It is important to consider the specific context or application when calculating energy usage per kilogram.
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.
A combustion reaction occurs when a substance usually containing carbon reacts with what to produce energy in the form of heat and light?
oxygen
How many rpm is needed to produce 2 V of electricity?
The RPM required to produce 2 V of electricity depends on the specific generator being used. Generally, higher RPM will produce higher voltage. You would need to consult the generator's specifications or conduct tests to determine the exact RPM needed to generate 2 V of electricity.
What is the principle of efficacy?
The principle of efficacy refers to the ability of a drug or treatment to produce a desired effect under specific conditions. It demonstrates the capacity of a medication to achieve its intended therapeutic outcome. In pharmacology, efficacy is distinct from potency, which refers to the strength or concentration of a drug required to produce a particular effect.
What are chemical principles?
Principles are the constituents of a substance. Chemical principles are those that produce a certain quality or effect in the substance.
How are cells able to produce the proteins required by certain conditions?
Cells produce proteins required for specific conditions through a process called gene expression. When a certain condition arises, signaling pathways activate specific genes, leading to the transcription of DNA into messenger RNA (mRNA). This mRNA is then translated by ribosomes into proteins that carry out functions necessary for the cell to adapt to the changes. Additionally, post-translational modifications can further tailor these proteins for their specific roles in response to the condition.
A certain mutant bacterial cell cannot produce substance X?
The mutant bacterial cell has a genetic mutation that impairs its ability to produce substance X. This mutation likely affects one of the genes involved in the biosynthesis pathway of substance X, leading to the cell's incapacity to synthesize it. This can impact the cell's metabolism, growth, and survival depending on the importance of substance X to its function.
Are enzymes highly specific?
Yes, enzymes are highly specific in terms of the reactions they catalyze. Each enzyme typically acts on a specific substrate to produce a specific product. This specificity is due to the precise three-dimensional structure of the enzyme, which allows it to interact only with certain substrates.
How does the chemical reaction of alcohol result in the formation of a colored substance?
When alcohol undergoes a chemical reaction, it can produce a colored substance due to the formation of new molecules with specific light-absorbing properties. This change in molecular structure can lead to the absorption and reflection of certain wavelengths of light, resulting in the perception of color.
Does a spermolytic substance produce sperm cells?
spermolytic is substance that destroys sperm
How do I convert btu hr into lbs hr?
If The amount of energy required to produce 34.5lbs/hr of steam at a pressure and temp of 0 psig and 212degree F with feed water 0 psig and 212 degree F requires 33445.6 Btu/hr of energy ie 33445.6 Btu/hr willl produce 34.5lbs/hr then mathematically it can be solved Thank you,
When substance burn in air what does it produce?
When a substance burns in air, it typically produces carbon dioxide and water vapor, along with any other byproducts specific to the substance being burned. The reaction of the substance with oxygen in the air releases energy in the form of heat and light.
Do insects produce milk?
Yes, certain species of insects, such as ants and cockroaches, produce a substance called "insect milk." This milk-like substance is a secretion from the brood cells of the insects and is rich in nutrients like protein and fats, which are essential for the growth and development of their offspring.
What is the substance known to produce or promote the development of cancer?
The substance known to produce or promote the development of cancer is carcinogens
What is inuculation?
To introduce a serum, vaccine, or antigenic substance into (the body of a person or animal), especially to produce or boost immunity to a specific diseaseRead more: inoculate
If a substance reacts with a metal to produce hydrogen gas what may you in infer about the substance?
If a substance reacts with a metal to produce hydrogen gas, it likely contains hydrogen ions (H+). This could indicate that the substance is an acid, as acids react with metals to produce hydrogen gas.
