Q. Assertion :Energy can be transferred between gaseous molecules during collisions but

u_{rms}

remains constant. Reason: The average kinetic energy of gaseous molecules remains constant as long as the temperature is constant and therefore,

u_{rms}

remains unchanged during the collision.

A charged particle moves through a region of magnetic field pointing in the direction perpendicular to its direction of velocity. Then during its subsequent motion,

(1)	Its momentum changes but the kinetic energy remains constant.
(2)	Its momentum and kinetic energy both changes.
(3)	Its momentum and kinetic energy both remains constant.
(4)	Its kinetic energy changes but the momentum remains constant.

Q. Statement I
As ice absorbs heat and begins to melt, its temperature remains constant
Because
Statement II
Changes of state bring about changes in a substances potential energy, not in its kinetic energy

Q. Assertion: In elastic collision, kinetic energy is conserved
Reason: Energy is always conserved.
MY PROBLEM
According to book Answer is (b) [both are true but reason is not the explanation of assertion]
Assertion is true but I think reason is false because Energy is conserved only in elastic collision and in Reason it is not mentioned whether it is elastic or inelastic.

Q. In an elastic collision
(a) the kinetic energy remains constant
(b) the linear momentum remains constant
(c) the final kinetic energy is equal to the initial kinetic energy
(d) the final linear momentum is equal to the initial linear momentum.
