Protons, neutrons, and electrons are the fundamental subatomic particles.
Humans sweat to expel toxins.
They also sweat because sweat helps the body cool down. During exercise, body temperature rises, sweat helps the body cool down.
Sweat also contain sodium. Which is why it’s salty.
Answer:
500J (joules)
Explanation:
since heat is is the product of mass, change in temperature, and specific heat, the solution can be found from the equation q = mcΔt, heat is 50 * .5 * 20 = 500J
Answer: Water
Explanation:
Chemically speaking, a solution has two components: solute and solvent.
The <u>solute</u> is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and <u>its proportion in the resulting solution is usually less than the solvent.
</u>
The <u>solvent</u> is the substance used to <u>dissolve the solute, and generally its proportion in the resulting solution is greater.</u> Being the most common used solvent water.
This means that in a solution there is usually more solvent than solute.
So, in the case of the hydrogen peroxide solution, since the proportion is
to
, the hydrogen peroxide is the solute and water is the solvent.
Answer:
from the warm object to the cool object
Explanation:
Think of heat as a straight line, and the warmer the object the higher its gradient. Now, if you have cold object is lower in heat energy, the heat energy from the warm object will go down the gradient to the cool object. Note, in conduction, there must a contact between the two objects.
