Well, there is kinetic energy when the object is in motion. But it will stop eventually because that energy is converted into thermal energy, or heat.
The concentration of the acid decreases
Answer:
<h2>1.806 × 10²⁴</h2>
Explanation:
The number of molecules can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 3 × 6.02 × 10²³
We have the final answer as
<h3>1.806 × 10²⁴</h3>
Hope this helps you
The aluminium substances would retain the most heat for the longest period of time.
<h3>What is retaining heat?</h3>
Retaining of heat is the quantity of heat that a substance or medium can store over time or the amount of heat that a specific amount of that substance can hold in itself. Substances that store heat 'well' (for a long time) also require a long time to heat up.
Copper and aluminium have the highest thermal conductivity among the more common metals, whereas steel and bronze have the lowest. When determining the metal to utilise for a certain application, heat conductivity is a critical quality to consider.
In addition, potassium has the highest specific heat and the longest heat retention time. Polystyrene, a polymeric polymer, can retain heat for up to 11 hours. This implies it can hold heat for extended periods of time.
Hence the aluminium substances would retain the most heat for the longest period of time.
