Correct answer is C
\(\theta\)p = 2\(\theta\)q
mq = 2mp
Cp X mp X \(\theta\)p = Cq x mq x \(\theta\)q
\(\frac {C_pm_q\theta q}{C_qm_p \theta q}\) = \(\frac {\theta q \times 2mp}{2 \theta qmp}\)
\(\frac {C_p}{Cq}\) = \(\frac {2}{2}\)
150cm3
273cm3
327cm3
600cm3
Correct answer is C
\(\frac{V_1}{T_1}\) = \(\frac{V_2}{T_2}\)
\(\frac{300}{27 + 273}\) = \(\frac{V_2}{54 + 273}\)
V2 = 327cm3
Which of the following properties makes metals ideal for cooking utensils?

No explanation has been provided for this answer.
Mercury is suitable as a barometric fluid because it?
expands uniformly
is opaque
is several times denser than water
is a good conductor of heat
Correct answer is C
Mercury is employed in the barometer because its density is sufficiently high for a relative short column to be obtained.
