Answer:
Explanation:
Hello, in this case, the lead is catching heat and the water losing it, that's why the heat relation ship is (D is for Δ):
Now, by stating the heat capacity definition:
Solving for the equilibrium temperature:
Which is very close to the water's temperature since the lead's both mass and head capacity are lower than those for water.
Best regards.
I would say C. petroleum
A is wrong
B is impractical for "mainly used"
D thats too expensive
The earth's mantle will not change in the future because this region is safe from the intervention of human beings.
<h3>What happens in the Earth's mantle?</h3>
The transfer of heat and material in the mantle helps us to determine the landscape of Earth. Activity in the mantle moves the plate tectonics, that contributes to volcanoes, seafloor spreading, earthquakes, and building of mountains.
So we can conclude that the earth's mantle will not change in the future because this region is safe from the intervention of human beings.

Metal solids contain a positively-charged cation surrounded by a "sea" of delocalised, negatively-charged electrons.
The electrons are able to move freely, and hence transfer kinetic energy throughout the implement at a much quicker rate than non-metals.
Plastic is made of non-metals (Mostly carbon and hydrogen) and therefore is a poor thermal conductor.
Therefore, by coating the metal utensil in plastic, the rate of heat energy transfer to the person in contact's hand is decreased.
