Answer:
−6063.54 J of heat is removed from the system during this process.
Explanation:
Given that :
in an isothermal process
number of moles of an ideal gas = 1.59 moles
which is compressed to one- fifth of its initial volume
Let say the initial volume = x
the final volume will be = x/5
Temperature = 285 K
The objective is to determine what quantity of heat is added to, or removed from, the system during this process.
In an isothermal process;
q = w
where ;
w = nRT In (V₂/V₁)
w = 1.59 × 8.314 × 285 × In (x/5 /x)
w = 1.59 × 8.314 × 285 × In (1/5)
w = −6063.54 J
Thus; −6063.54 J of heat is removed from the system during this process.
Using evidence to support explanations is a good practice because it proves that what you are explaining can be verified.
You'll need the specific heat capacity of aluminium to solve this question.
H=(0.005)(37-22)(specific heat capacity of aluminium)
Answer:
Periods
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
