The material which requires the most heat to raise its temperature from 10°C to 30°C is oil.
<h3>What is the formula to calculate absorbed heat?</h3>
The formula which we used to calculate the amount of involved heat in relation with specific heat is:
Q = mcΔT, where
- Q = absorbed heat
- m = mass
- c = specific heat
- ΔT = change in temperature
Among the given materials, specific heat of oil is highest than other materials so will require maximum absorbed heat.
Hence, oil requires the most heat.

Answer:
C + O2 → CO2
Explanation:
C + O2 → CO ----------------- (1)
from equ (1) on reactant side, C has 1 mole, O has 2 moles
from equ (1) on product side, C has 1 mole, O has 1 mole
Thus, to balance the equation, O should have 2 moles
C + O2 → CO2
Answer: Elements in Group 2
Explanation: The periodic table was arranged by Dmitri Mendeleev specifically around similarites in their chemical behaviors. He found that as atomic number increases, at some point an element starts to react in a manner similar to a previous one. When that happened, he would place the larger element under the smaller one, and eventually noticed a periodicity in the table. Elements in a column (Groups) had similiar chemical properties. We know today that these similarities are due to the electron configuration, and that these configurations repeat themselves. He left gaps in the table when he could find an existing element with properties similar to others in that group. I big leap of faith, but it worked. Elements for those missing boxes were eventually discovered.
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. Hope this helps! :D
