1.
Pure water reaches its maximum density (1.000 g/cm3 or 1000 kg/m3) at a temperature of:
0.0 °C
25.0 °C
-4.0 °C
4.0 °C
2.
The density of an ideal gas at temperature T and pressure P is rho. If the pressure is tripled and the absolute temperature is halved, the new density becomes:
6 rho (since rho is proportional to P / T)
0.67 rho
3 rho
1.5 rho
3.
In a pure capacitor circuit connected to an AC source, the average power consumed over a full cycle is:
B) \(I_{text{eff}}^2 times X_C\)
D) \(0.5 times V_{max} times I_{max}\)
A) \(V_{text{eff}} times I_{text{eff}}\)
C) Zero
