Correct answer is D
\(MC_{p}\ \times 2\theta^2\ = mc\theta\ \times \theta\) ; \(\frac{C_{p}}{CQ}\) = \(\frac{m}{2mo}\)
81°C
162°C
354°C
627°C
900°C
Correct answer is D
\(\frac{V_{1}}{T_{1}}\) = \(\frac{V_{2}}{T_{2}}\) x \(\frac{V_{1}}{27+273}\) = \(\frac{3V_{1}}{T_{2}}\) , \(T_{2}\)= 900K; T=627°C
33.6°C
35.0°C
37.3°C
52.7°C
62.7°C
Correct answer is C
\(\frac{x - 0}{100 - 0} = \frac{33.6 - 0}{90 - 0}\)
\(\frac{x}{100} = \frac{33.6}{90}\)
\(90x = 3360 \implies x = \frac{3360}{90}\)
= 37.3°C
