V1 = 0.0043m^3,P1=121560Pa,T1=310K then goes through an adiabatic compression to V2=0.00076m^3,P2=?,T2=? given gamma = 1.4

i did!

Homework Statement A mass of gas occupies a volume of 4.3L at a pressure of 1.2 atm and a temperature of 310K. It is compressed adiabatically to a volume of 0.76L.Determine (a)the final pressure and (b) the final temperature,assuming the gas to be an ideal gas for which gamma = 1.4...

Sorry,melting point of lead - the initial temperature? cheers

i have found the specific heat of lead to b 0.0305. I have the mass of lead 130 J/kg.degree celsius By using that, how am i able to find the amount energy used to increase the temperature of the bullet? i need the change in temperature?would that be the melting point of lead? then q=0.5mv^2?

i'm still a bit confused,sorry,not really that good at this part in physics! specific heat is energy required to increase the temperature by 1 degree. not really sure how this applies to this question. cheers

1. Homework Statement hey guys, i am new in this forums and would love help with a question i have encountered with an assignment that i am doing.The question is : At a crime scene, the forensic investigator notes that a 8.2g lead bullet that was stopped in a door frame apparently melted...
