1. Please answer each of the following questions: [1x10=10] a) Give an example which indicates that waves are nothing but disturbance in a field.
b) The difference between angular frequency and frequency is.
c) For explaining kinetic theory of gases, which types of velocity can be considered?
d) In a mug, you took coffee powder, sugar and milk to make coffee. The temperature of the milk
and the coffee powder are 45°C and the sugar is in thermal equilibrium with both of them. What will
be the thermal state of the sugar?
e) A gas in a closed container is heated with 12J of energy, causing the lid of the container to rise 3m
with 5N of force. What is the total change in energy?
f) A ball is dropped from a certain height onto the floor and keep bouncing. Is the motion is simple
harmonic? Explain.
g) Out of a solid, liquid and gas of the same mass and the same temperature, which one has the
greatest internal energy? Which one has the least?
h) A pendulum on a planet, where gravitational acceleration is unknown, oscillates with a time period
5 sec. If the mass is increased six times, what is the time period of the pendulum?
i) “Energy can neither be created nor be destroyed- only converted from one form of energy to
another”- this leads us to a law of thermodynamics. What is it?
j) When we mix hot and cold water together, it forms warm water and increases the entropy. This
example leads us to the statement that “All real processes are irreversible”. Explain this situation in
short.
