1.	Class: 9thMax.marks: 15Give short answers:1. Define specific heat capacity. How would you find the specificheat capacity of solid2.Write a note on linear thermal expansion in solids.3. How much heat is required to increase the temperature of 0.5kgof water from 10C to 65C ?
Answer» EXPLANATION: specific heat of a solid or LIQUID is the amount of heat that raises the temperature of a UNIT mass of the solid through 1° C. We symbolise it as C. In S.I unit, it is the amount of heat that raises the temperature of 1 kg of solid or liquid through 1K. Its unit in S.I system is always given as J kg-1 K-1 and CGS as cal g-1 C-1. If the amount of heat, ∆Q, required to raise the temperature of mass M through ∆T...........answer to the 1st QUESTION
