Answer:
234 KJ ≡ 55.887 Kcal
Explanation:
∴ J ≡ Kg/m².s² ≡ N.m = 0.2389 cal
∴ cal = 4.187 J
⇒ 234 KJ * ( 1000 J / KJ ) * ( cal / 4.187 J ) * ( Kcal / 1000 cal ) = 55.887 Kcal
A hot metal with a low heat capacity will raise the final temperature of water more than a hot metal with high heat capacity.
<h3>Heat capacity</h3>
It is the amount of heat required to change the temperature of a substance by just a unit.
Substances that heat up quickly are said to have low heat capacities while those that take time to heat up are said to have high heat capacities.
Substances with low heat capacity also release their thermal energy quicker than those with high heat capacity.
Thus, a hot metal with low heat capacity will readily transfer its thermal energy to water than a hot metal with high heat capacity.

A, the higher the temperature, the faster the average kinetic energy
Answer:
Both b/c a chemical formula tells you how many and a sketch formula shows how they are bonded together.
Molecular formulas show how many atoms of each element one molecule of a compound contains. Note: Ionic compounds are generally crystalline solids with high melting points. Other compounds, however, have very different properties.
It will determine the volume of an irregular object like a rock.
