Answer:
<u>The amount of energy required to increase temperature 275°C to 385°C is ΔQ =3.95208kJ</u>
Explanation:
Given :
- <em>The mass of the water vapour is 18 g</em>
- <em>The initial temperature : 275°C</em>
- <em>The final temperature : 385°C</em>
According to the formula :
Δ
Δ
Where ,
- <em>Δ
is the heat supplied</em> - <em>
is the mass of the substance (water vapour) = 18g</em> - <em>
is the specific heat of the substance ( water vapour) = 
</em> - <em>Δ is the change in temperature =
</em>
∴
ΔQ = 
⇒ΔQ =3.95208kJ
Hi.
I did some digging and I think I found what you're looking for.
I found this on Q(uizlet)
basic or acidic conditions and the reactants must be heated.

Explanation:
use the equilibrium equation
Answer:
True True False
Explanation:
Valves are in most veins (to prevent backflow). Also valves in the chart and an in an combustion engine.
So the first statement is True.
Valves control the flow rate and direction of fluid within a closed system. So the second statement is True.
1 Pa = 1 N/m² So since 1 Pa equals to one newton per square metre the third statement is False.
