3. a) What do you understand by the specific heat capacity of a substance? b) A lump of pure ice of mass 20 g and at a temperature of 0.0 °C is dropped into a well-insulated calorimeter (of negligible specific heat capacity) containing 210 g of alcohol at a temperature of 23.0 °C. After stirring properly, the mixture attains an equilibrium temperature of 8.4 °C. (i) State one similarity between the molecular properties of ice and alcohol (liquid).

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
