Answer:
Because one calorie is equal to 4.18 J, it takes 4.18 J to raise the temperature of one gram of water by 1°C. In joules, water's specific heat is 4.18 J per gram per °C. If you look at the specific heat graph shown below, you will see that 4.18 is an unusually large value.
Answer: Melting point and boiling point
Explanation:
Chemical Reaction
Answer:
The movement of electrons is kinetic energy, capable of producing electrical energy (option B).
Explanation:
An electron is a mobile subatomic particle, located outside the atom and forming elliptical orbits, unlike protons and neutrons. In addition, each electron has a negative charge.
<u>The energy on which the movement of the electrons depends is kinetic energy, which promotes this movement</u>. The interaction between the negative charges of the electrons and the positive charge of the protons produces electrical energy.
<em>The other options are not correct because the charge energy, electric energy and magnetic energy are consequences of the activity of the subatomic particles of the atom.</em>
Answer:
The answer is
<h2>2.64 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 611 g
volume = final volume of water - initial volume of water
volume = 256.7 - 25.1 = 231.6 mL
The density of the metal is

We have the final answer as
<h3>2.64 g/mL</h3>
Hope this helps you
