Title: The specific heat of copper is 0.385 J/(g ⋅ °C). If 34.2 g of copper, initially Post by: madiward on Nov 11, 2015 The specific heat of copper is 0.385 J/(g ⋅ °C). If 34.2 g of copper, initially at 21.0°C, absorbs 4.689 kJ, what will be the final temperature of the copper?
Title: Re: The specific heat of copper is 0.385 J/(g ⋅ °C). If 34.2 g of copper, initially Post by: bio_man on Nov 15, 2015 Heat absorbed = (mass Cu)(sp. ht. Cu)(Tf - Ti)
4689 J = (34.2 g)(0.385 J / g C)(Tf - 24.0 C) 4689 = 13.2Tf - 316 5005 = 13.2Tf Tf = 379 C |
