A2-kilogram block of which material would require about 450 j and thermal energy to increase its temperature by 1°c

a block whose heat capavity was 450/2 j/kg   ... 225j/kg

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
