4200J
1600J
24000J
96000J
Correct answer is D
Q = I2RT
= 42 x 50 x 2 x 60
= 96000J
105J
3255J
3465J
16821J
Correct answer is C
Q = ML + MC\(\theta\)
= 10 x 335 + 10 x 2.1 x 5
= 3465J
The volume of a given mass of gas at 27oC and 800 mmHg is 76cm2. Calculate its volume at s.t.p
100.0 cm3
72.8 cm3
60.0 cm3
36.4 cm3
Correct answer is B
\(V_2 = \frac{P_1V_1T_2}{P_2T_1} = \frac{800 \times 76 \times 273}{760 \times 300}\)
= 72.8cm3
