The specific heat of a certain type of metal is 0.128 j/(gâ·â°c). what is the final temperature if 305 j of heat is added to 26.5 g of this metal initially at 20.0 â°c?

We know the heat gained

#DeltaH=mxxsxx(t_2-t_1)#

where

#DeltaH=305J#
#m->"mass"=83g#

#s->"sp heat"=0.128" J/(g^@C)#

#t_1->"initial temperature"=20^@C#

#t_2->"final temperature"=?#

So

#DeltaH=mxxsxx(t_2-t_1)#

#=>305J=83gxx0.128J/(g^@C)xx(t_2-20)^@C#

#=>t_2-20=305/(83xx0.128)#

#=>t_2=48.7^@C#

the answer for sodium is 0.186

the answer for rubidium is 0.251

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
