The final temperature of the water is determined as 50.55 ⁰C.
<h3>
Final temperature of the water</h3>
The final temperature of the water is determined from the following calculations;
Q = mcΔθ
Δθ = Q/mc
where;
- Q is the amount of energy = 81 kcal = 338904 J
- c is specific heat capacity of water = 4,200 J/kgC
Δθ = 338904 /(3.5 x 4200)
Δθ = 23.05 °C
Final temperature = T₁ + Δθ
Final temperature = 27.5°C + 23.05 °C = 50.55 ⁰C.

In quantum matter, all things in the world are made up of even smaller particles than the atom. These are called the subatomic particles: neutron, proton and electron. A beta particle is simply an electron. It is an electromagnetic particle or wave. Electromagnetic particles are high-energy particles that are emitted by the atom during radioactive decay. Since it is an electron, its charge must be -1 and it must come from outside the nucleus of the atom. From the choices, the answers would be:
<span>is electromagnetic energy
</span><span>has a -1 charge</span>
The domain that is an onion is the <span>Eukaryote.
