I think ive got this but not 100% sure.(adsbygoogle = window.adsbygoogle || []).push({});

if a horse can heat 11.6kg ice water T=273k to 355K in 2.5 hours how high could it raise a 217kg weight in 2.5 min?

heres what ive done

q_{p}=mc_{p,s}dt=(1.16E4 g)(4.18 J K^{-1}g_{-1})(82K)=3.976E6 J

(3.976E6 J/2.5hr)(1hr/60min)(2.5min)=6.627E4 J

h=w/mg=6.627E4 J/((217 kg)(9.81m s^{-2}))=31.1m

does this seem legit? we working with all this rev/irr-rev work and transfer and im getting really mixed up by simple stuff but if p=const then it would be irreversible right?

any suggestions would be great if im way off track

Thnaks
