Correct answer is B
Elect. energy = heat energy
IVt = mL
20 X 12 t = 1.5 x 336 x 103
t = 2100 sec ; t = 35mins.
1200cm3
1378cm3
4320cm3
4629cm3
Correct answer is A
\(\frac{V_1P_1}{T_1}\) = \(\frac{V_2P_2}{T_2}\)
\(\frac{70 \times 1200}{7 \times 273}\) = \(\frac{75 \times V_2}{27 + 273}\)
V2 = 1200cm3
A column of air 10.0cm long is trapped in a tube at 27oC. What is the length of the volume at 100oC?
12.4cm
13.7cm
18.5cm
37.0cm
Correct answer is A
\(\frac{V_1}{T_1}\) = \(\frac{V_2}{T_2}\)
\(\frac{10\times A}{27 + 273}\) = \(\frac{L\times A}{100 + 273}\)
L = 12.43cm

Correct answer is B
100\(\theta\) .... 875mm
0\(\theta\) ....325mm
\(\theta\) .... 190mm
\(\frac{0 - \theta}{100 - \theta}\) = \(\frac{325 - 190}{875 - 190}\)
\(\theta\) = -25oC
= 243k
