Granite is stronger, and it doesn't grow mold in the rain. It also looks better than marble and is easier to carve.
Answer: Matter is heated, and its particles spread out more
Explanation:
Thermal expansion occurs when there's an expansion of an object or material or when an object becomes bigger because of a rise in its temperature. This brings about the faster movement of the heated molecules and the atoms spreading out.
Therefore, the cause and effect of thermal expansion will be that when matter is heated, and its particles spread out more.
Answer:
0.155836449023405
Explanation:
The molecular formula for Methane is CH4.
The SI base unit for amount of substance is the mole.
1 grams Methane is equal to 0.062334579609362 mole.
<span>Enthalpy
change is the total heat that is absorbed or evolved in a certain reaction that
is being carried in a constant pressure system. It can be calculated by the
product of the specific heat of the substance and the difference of the final
temperature and the initial temperature. For this case, the enthalpy of combustion is given, so we simply multiply the amount of octane present to the enthalpy given to determine the total heat that is released.
Heat = 75 g ( 1 mol / 114.23 g ) (- 5500 kJ / mol ) = - 3611.14 kJ
The negative sign in the calculated value represents that this heat is being released in the process.</span>
