A 3`Omega` resistor show in figure is dipped into a calorimeter containing `H_(2)O` .The thermal capacity of `H_(2)O` + calorimeter is 2000J/K .If the circuit is active for 15 minutes find the rise in temperature of `H_(2)O`

The 2.0 Omega resistor show in figure is dipped into a calorimeter containing water. The heat capacity of the calorimeter together with water is 2000 J K^(-1) . (a) If the circuit is active for 15 minutes, what would be the rise in the temperature of the water? (b) Suppose the 6.0 Omega resistor gets burnt. What would be the rise in the temperature of the water in the next 15 minutes? (Figure)

Colloidal solution show in H_(2)O :-

A 1.250 g sample of octane (C_(8)H_(18)) is burned in excess of oxygen in a bomb calorimeter. The temperature of calorimeter rises from 294.05 K to 300.78 K . If heat capacity of the calorimeter is 8.93 kJ K^(-1) , find the heat transferred to calorimeter.

Compare the stuctures of H_(2)O and H_(2)O_(2) .

Arrange the following gases in order of their critical temperature. NH_(3),H_(2)O,CO_(2),O_(2)

Compare the chemical properties of H_(2)O and H_(2)O_(2) .

Two closed vessels A,B are at the same temperature T and contain gases which obey Maxwellian distribution of velocities. Vessel A contains O_(2) , and B contain mixture of H_(2) and O_(2) . If the average speed of the O_(2) molecule in vessel A is V_(1) , then average speed of H_(2) in container B is

For the process, H_(2)O(l) to H_(2)O(g)

The dipole moment of H_(2)O_(2) is more than that of H_(2)O but H_(2)O_(2) is not a good solvent because :
