Write the note on isochoric process.

Explanation

The process during which the volume of system remains constant is known as isochoric process.
Volume V is constant in isochoric process,
`therefore` Work , `W=PDeltaV , DeltaV=0`
`therefore W=0`
Now, from first law of thermodyanmics ,
`DeltaQ=DeltaU+DeltaW, DeltaW=0`
`therefore DeltaQ=DeltaU`
Hence, heat absorbs and internal energy increases.
Means temperature increases and when gas reject heat, internal energy decreases means temperature decreases.
The change in temperature for a given amount of heat can be determine bythe specific heat capacity of gas at constant volume by the formula.
`C=(DeltaQ)/(muDeltaT)`
`therefore DeltaT=(DeltaQ)/C` [`mu` is known]
