Energy required = Specific Heat × mass × change in temp.
<span>Specific Heat (Cp) water = 4.186kJ/kgC </span>
<span>Mass = 20kg </span>
<span>Change in temperature = 35C - 0C = 35C </span>
<span>Q = 4.186kJ/kgC × 20kg × 35C = 293.02kJ hope this helps! (:</span>
Answer:3H2O + light-c3h603+302
Explanation:
This statement is True, Because the phenomenon is called a Mirage!
Answer: <span>Protons do not move out of the nucleus of atoms although they repel each other.
Reasoning:
Remember that protons are particles with positive charge and they held together in the nucleus of the atom which is a tiny tiny region. As you know, like charges repel each other, which means that the protons exert a repulsion force.
That repulsion force tends to destabilize the atom. The only reason why the atom does not explode is because there is a there exists a force of attraction that exceeds the repulsion of the like charged protons. That is the strong nuclear force. Therefore, the strong nuclear forces are stronger than the electromagnetic force that tends to get the protons apart.
