Question 8. PV = nRT, solve for T please?<br><br>Question 10. C= Wtc÷1000, solve for W, please?

sp2606 [1]

Answers:

$\huge \boxed{T= \frac{P V}{n R} } \\ \\ \\ \\ \huge \boxed{W= \displaystyle \frac{1000C }{tc}}$

$\rule[225]{225}{2}$

Step-by-step explanation:

$P \cdot V = n \cdot R \cdot T$

Dividing both sides by n · R:

$\displaystyle \frac{P \cdot V}{n \cdot R} =T$

$\displaystyle C=\frac{Wtc }{1000}$

Multiplying both sides by 1000:

$1000C=Wtc$

Dividing both sides by tc:

$\displaystyle \frac{1000C }{tc}=W$

$\rule[225]{225}{2}$
