Question
Equal amounts of energy are added to equal masses of two different metals. The first metal experiences a temperature change of T1.
Derive an equation for the temperature increase of the second metal compared with the temperature increase of the first metal.
A certain amount of heat added to 65 grams of lead causes a temperature change of 15 degrees celsius. Calculate the temperature change when the same amount of energy is added to 65 grams of copper.
Explanation / Answer
LET SPECIFIC HEAT OF METAL 1= S1 METAL2= S2 so by heat gained= heat lost heat change in first metal= ms1 ?T1 for 2nd change will be=> m s2 ?T2=ms1?T1 so ?T2=s1 ?T1/s2 --------------------ans s1=( Slead/s copper )*15 =0.031/0.092 *15=31*15/92=---------------sove =ans 0.031 (kcal/kgoC------lead 0.092 (kcal/kgoC---copper
