MCQ

A product from a chemical industry passes through three states - gas, liquid, solid. The product is initially formed in gaseous state which is then liquefied and finally solidified. For same mass (say 5g) which state has maximum internal energy?

A
Solid
B
Liquid
C
Gas
D
All have equal internal energy

✓

Answer

Gas

Explanation

Internal energy is dependent on the freedom of movement of particles. Since in gaseous state, particles are most free to move, this state has maximum internal energy.

Free ²³⁸U nuclei kept in a train emit alpha particles. When the train is stationary and a uranium nucleus decays, a passenger measures that the separation between the alpha particle and the recoiling nucleus becomes x in time t after the decay. If a decay takes place when the train is moving at a uniform speed v, the distance between the alpha particle and the recoiling nucleus at a time t after the decay, as measured by the passenger will be:

x + vt
x - vt
x
depends on the direction of the train.
