Heat capacity (CV) of an ideal gas is X KJ/ mole/K. To rise its temperature from298 K to 318 K, heat to be supplied per 10g gas will be (in KJ) [MW =16]

The working of an electric bell is based on the :

When an electric current flows through the electric bell, ___________ is attracted towards the electromagnet.

The correct statements of the following : a) Hysteresis loop is wide for permanent magnets and narrow for electromagnets. b) If another medium is introduced between the poles instead of air, force may increase (or) decrease. c) Angle of dip is +ve in the northern hemisphere and negative in the southern hemisphere of earth. d) Magnetic compass placed at the geomagnetic north pole shows geomagnetic south.

Which of the following is not a component of an electric bell?

Heat capacity (C_V) of an ideal gas is X KJ/ mole/K. To rise its temperature from298 K to 318 K, heat to be supplied per 10g gas will be (in KJ) [MW =16]
