<h3>Answer :</h3>
<h3>Specific Heat</h3>
<h3>Explanation :</h3>
<h3>The specific heat represents the amount of energy required to raise 1 kg of substance by 1oC (or 1 K), and can be thought of as the ability to absorb heat. The SI units of specific heats are J/kgK (kJ/kgoC). Water has a large specific heat of 4.19 kJ/kgoC compared to many other fluids and materials.</h3>
I hope it'll help
thanks...
Modern atomic theory is, of course, a little more involved than Dalton's theory but the essence of Dalton's theory remains valid. Today we know that atoms can be destroyed via nuclear reactions but not by chemical reactions. Also, there are different kinds of atoms (differing by their masses) within an element that are known as "isotopes", but isotopes of an element have the same chemical properties.
Many heretofore unexplained chemical phenomena were quickly explained by Dalton with his theory. Dalton's theory quickly became the theoretical foundation in chemistry.
Answer:
The average kinetic energy of a gas depends only on its temperature.
Explanation:
The average kinetic energy of particles in a gas can be found using the equation
,
where
- is the Stefan-Boltzmann constant, and
- is the absolute temperature of this gas (the one in degree Kelvins.)
As seen in this equation, the average kinetic energy of particles in a gas depends only on the temperature of the gas. Also, since the question is asking for the average not the total kinetic energy, the number of particles in this gas doesn't matter, either.
Answer:
8.1m/s2
Explanation:
The following were obtained from the question:
V = 24.3m/s
t = 3secs
a =?
a = V / t
a = 24.3 / 3
a = 8.1m/s2
I think it's D cuz gasoline is technically a chemical so chemical energy. and the Engine which is working is mechanical or kinetic
so d. first from chemical to mechanical
hope i helped thnx
